Description: The Rectifier Module Mounting Shelf and Rectifier Modules (PCUs), when used in a NETSURE Power System equipped with a Meter-Control-Alarm (MCA) Assembly, comprise a -48V DC Power System designed to power a load while charging a positive grounded battery. This system is capable of operating in a battery-less installation or off battery for maintenance purposes. The system is designed for operation with the positive output grounded.

The NETSURE Power System utilizing this equipment is a complete integrated power system containing rectifiers (PCUs), intelligent control, metering, monitoring, and distribution. A NETSURE Power System, utilizing this equipment, typically consists of...

Rectifier Module Mounting Shelf The system contains one or more Rectifier Module Mounting Shelves, each of which houses up to six (6) Rectifier Modules (PCUs).

Rectifier Modules (PCUs) The system contains Rectifier Modules (PCUs), which provide load power, battery float current, and battery recharge current during normal operating conditions. The Rectifier Modules (PCUs) are a constant power design. This means that, within the normal operating ambient temperature range, the maximum output power available is a constant 3200W or 3500W. Within this ambient temperature range, the Rectifier Modules (PCUs) will operate in one of three modes, depending upon load demands. Transition between modes is completely automatic.

Constant Voltage Mode: For any initial output voltage setting from 47 to 58 volts, output voltage remains constant regardless of load. This is the normal operating condition, in which loads are being supplied and batteries are float charged. Rectifier Modules (PCUs) will operate in the Constant Voltage Mode unless load increases to the point where the product of load current and output voltage is approximately 3200W or 3500W.

Constant Power Mode: As load increases above approximately 3200W or 3500W (non-adjustable), output current continues to increase, but output voltage decreases as required to maintain constant output power. Rectifier Modules (PCUs) will operate in the Constant Power Mode unless load continues to increase to the point where the current limit setting is reached.

PD588705000 Power Data Sheet Issue AJ, January 18, 2011 Spec. No. 588705000 (Model PSS4850-23GV)

Constant Current Mode: If load increases above the current limit setting, output voltage decreases linearly to maintain output current at current limit.

Rectifier Modules (PCUs) continue to operate in higher ambient temperatures, but at reduced power. Refer also to Paragraph 1.4.6 under SPECIFICATIONS.

Meter-Control-Alarm (MCA) Assembly The system contains one MCA. The MCA controls the operation of the Rectifier Modules (PCUs). The MCA also provides power system control, metering, monitoring, and alarm functions. Note: This document does not describe the MCA. Refer to the Power System SAG (System Application Guide) for MCA information.

1.4 Standard Features

1.4.1 Type of Power Conversion Circuit: High frequency.

1.4.2 Float Charging Output Mode: In this mode of operation, system output voltage is constant and output current does not exceed the current limit setting. During normal operation, the battery is not required to furnish load current and remains in a fully charged condition.

The float voltage setting can be checked and/or adjusted without removing a Rectifier Module or affecting the load. One adjustment changes the output of all Rectifier Modules.

Note: If the current demanded by the load exceeds the current limit setting of the system, the battery is required to furnish the difference in load current and begins discharging.

Note: If the system is used with a digital battery charge temperature compensation probe or TXM, the MCA automatically adjusts system output. This ensures proper voltage to the battery as battery ambient temperature fluctuates.

1.4.3 Test/Equalize Charging Output Mode: This mode of operation is used if higher output voltage is required for equalizing the charge on all battery cells of a conventional flooded cell battery, or for recharging the battery following a commercial power failure.

If the installation site does not require system equalize mode of operation, the equalize feature can be used as a test feature. System equalize voltage can be adjusted to a test voltage value. Placing the system into the test/equalize mode causes system output voltage to increase or decrease to this test voltage value.

The test/equalize voltage setting can be checked and/or adjusted without removing a Rectifier Module or affecting the load. One adjustment changes the output of all Rectifier Modules.

Note: If the system is used with a battery charge digital temperature compensation probe or TXM, typical equalize mode of operation is not used.

1.4.4 Output Mode of Operation Selection: There are four methods of placing the system from the float mode to the test/equalize mode.

(A) Method 1 (Manual Test/Equalize): A user manually places the system into the test/equalize mode via the MCA interface. A user must manually return the system to the float mode via the MCA interface.

Home

Page 28 of 41



(B) Method 2 (Manually Initiated Timed Test/Equalize): A user manually places the system into the test/equalize mode via the MCA interface. The system automatically returns to the float mode after a preset programmable time period (1-99 hours, in increments of one hour).

(C) Method 3 (Automatic Test/Equalize):

THE AUTOMATIC EQUALIZE FEATURE IS INTENDED FOR USE ONLY WITH WET CELL BATTERIES. USING THIS FEATURE WITH VALVE REGULATED BATTERIES IS NOT RECOMMENDED.

This feature can be enabled or disabled by a user via the MCA. The default state is disabled.

The Automatic Equalize feature is a time based function that is controlled by a customer selectable multiplier and by the Battery On Discharge (BOD) alarm setpoint. The MCAs default setting is for a multiplier of zero, which disables the Automatic Equalize feature.

When the Automatic Equalize feature is enabled, if system voltage drops to less than the BOD alarm setpoint, the MCA initiates a timing cycle to measure the discharge time period. The MCA requires at least 15 minutes of continuous BOD alarm in order to prevent nuisance equalization cycles. When system voltage rises to above the BOD alarm setpoint, the MCA ends the discharge timing cycle and (assuming a minimum of 15 minutes has elapsed) places the Rectifier Modules into the equalize mode for a customer selectable multiple of the discharge time period (the discharge time period includes the initial 15 minutes).

The equalize time period can be set for 0 to 15 times the discharge time period, up to a maximum of 300 hours. A zero (0) setting disables the feature.

(D) Method 4 (External Test/Equalize): A user (or external equipment) places the system into the test/equalize mode by applying an external signal to the system. The system returns to the float mode when the external signal is removed. This method overrides the other three methods.

1.4.5 Input Protection:

(A) Fuse: On the input two UL recognized fuses are used.

(B) Input Voltage Protection: Requirement of operating range is 85-290Vac. Derating from 176Vac and 50% at 120Vac. Withstanding 415Vac input w/o damage.

To fulfill these, the following actions will be taken.

1) The rectifier will shut down at low or high voltage input;

The protecting voltages are:

Low voltage disable point: 80V3V; Hysteresis at least 15 VAC for restart.

High voltage disable point: 295V5V; Hysteresis at least 10 VAC for restart.

2) Between 85V and 176V the output power will be derated linearly according input voltage as following.

For R48-3200 and R48-3200e, Output power (not less than) Vs input voltage and temperature.

Input voltage 45C 55C 65C 70C 75C

For R48-3500e, Output power (not less than) Vs input voltage and temperature.

Input voltage 45C 50C 55C 65C 70C 75C

85Vac 700 640 580 464 290 0

120Vac 1750 1600 1450 1160 725 0

176Vac 3500 3200 2900 2320 1450 0

For the stabilization, the output power can sluggishly change when input voltage fluctuate in a narrow range which not more than 3V.

3) Over voltage isolation

The rectifier will be disconnected from the mains when a preset non-adjustable value is reached.

(C) AC Fail Alarm: The rectifier issues an "AC Fail Alarm" when AC input voltage drops to 164Vac. This alarm clears when AC input voltage recovers to 169Vac.

1.4.6 Output Protection:

(A) Current Limiting: The maximum current delivered by the system can be programmed from 10% to 121% of total system capacity at maximum rated output voltage. The associated MCA automatically adjusts the current limit circuit on each Rectifier Module so that this value is not exceeded. If a Rectifier Module fails, the MCA automatically resets each remaining Rectifier Module's current limit point to maintain this value. The MCA also insures that the current limit circuit on any Rectifier Module is not set above 121% of its capacity. The default current limit setting is the sum of each installed Rectifier Modules output rating. If an additional Rectifier Module is added to the system, the system current limit is automatically increased by the rating of the new Rectifier Module and the new current limit value is displayed.

The current limiting point can be adjusted (via the MCA) without removing a Rectifier Module. One adjustment changes the setting of all Rectifier Modules.

The current limit is factory set at 100% of rated full load, unless otherwise specified.

Output Current Limit Error: 1.5A (at 42-58.5V), 3A (at 30-42V), 5A (20 < at < 30V). (B) Thermal Current Limiting: Each Rectifier Module continuously monitors the ambient

temperature surrounding the power conversion circuit. If this temperature for any reason (such as a high ambient temperature) increases above approximately +45C (+113F), the Rectifier Module will not shut down. Rather, the Rectifier Module will limit its maximum output power to maintain the temperature of the power conversion circuit within design parameters. Operation between +45C (+113F) and +65C (149F) will result in the output power being decreased. Full power capability is restored when the temperature decreases to below approximately +45C (+113F). Refer to the following curve (Figure 2) illustrating typical operating parameters.

Warning: The module is rated for continuous operation at full output power up to +45C (+113F). Operation between +45C (+113F) and +65C (149F) will result in output power decrease. Operation above +65C (+149F) is considered abnormal and should be used on a temporary1 basis only.

1 Temporary Operation at Abnormal Temperature: Temporary operation refers to a period of not more than eight consecutive hours per day, and a total of not more than 15 days in a year. (This refers to a total of 120 hours in any given year, but no more than 15 occurrences in that one year period.)

Typical Thermal Power Limit Curve

(C) High Temperature Alarm: Each Rectifier Module continuously monitors the ambient temperature surrounding the power conversion circuit. If this temperature exceeds a preset non-adjustable value, local and extended Rectifier Module Fail alarms are activated. The alarms will automatically be removed when the ambient temperature surrounding the power conversion circuit decreases to below a preset non-adjustable value.

(D) High Voltage Shutdown:

(1) Internal: If Rectifier Module output voltage exceeds an adjustable preset value and it is delivering more than 10% of its rated current, the Rectifier Module shuts down.

After approximately 6 seconds, the Rectifier Module automatically restarts. If Rectifier Module output voltage again exceeds the high voltage shutdown value within 5 minutes, the Rectifier Module shuts down and locks out. Manual restart is then required (by turning AC power to the Rectifier Module off or by removing the Rectifier Module, waiting 19 seconds or more, then turning AC power to the Rectifier Module on or re-inserting the Rectifier Module). If the Rectifier Module does not experience a high voltage condition within the 5-minute time-period, the restart circuit is reset.

If two or more Rectifier Modules are installed in a shelf, or if the shelf is paralleled with other Rectifier Mounting Shelves, only the Rectifier Module causing the high voltage condition shuts down.

The high voltage shutdown point can be checked and/or adjusted without removing a Rectifier Module. One adjustment changes the setting of all Rectifier Modules.

Adjustable from 48.00 to 59.00 volts DC. Refer to the separate Power System documentation for the factory setting.

(2) Remote: See associated Power System documentation.

(3) Backup: If Rectifier Module output voltage exceeds a second (non-adjustable) value, the Rectifier Module shuts down and locks out regardless of load. Manual restart is then required (by turning AC power to the Rectifier Modules off then on, or by removing and re-inserting the Rectifier Modules).

(E) Overload / Reverse Current: An output fuse is provided on each Rectifier Module. This fuse is not customer replaceable. The Rectifier Module can be plugged into or pulled out of a shelf while operating, without damage or opening the fuse.


1.4.7 Paralleling: This system may be connected in parallel with any rectifier of the same polarity and adjusted to the same output voltage.

1.4.8 Load Sharing:

(A) Rectifier Module Load Sharing (per Bay): The requirement is < 1.5A difference of average current of rectifiers at 10%~100% load for rectifiers in one cabinet (max 1320A).

The internal processors of rectifiers will control load sharing.

The maximum number of parallel rectifiers is 36.

(B) MCA Load Sharing (between two Bays): The MCA load sharing feature automatically balances the load to within 1% of the Bays' rated output currents. If the MCA's load sharing feature is disabled for any reason, pre-programmed slope control in each Rectifier Module balances the load in each bay as stated above. The MCA will balance a system of up to 72 Rectifier Modules within 5 minutes. The MCA's load sharing feature is disabled whenever the system is in current limit, the system is delivering more than 100% capacity, or the system is delivering less than 1% capacity.

MCA Load Share Alarm: The MCA balances the load by monitoring the output current of each Rectifier Module, and raising or lowering the output voltage of each Rectifier Module individually to reduce the output current differences between the Rectifier Modules. If one Rectifier Module is delivering less (or more) current than the others, the MCA slowly continues to increase (or decrease) that Rectifier Module's output voltage in an attempt to get its output current to equal the others. If, after about 15 minutes of trying, the MCA is unable to balance the output currents, the MCA turns on the Load Share Alarm and identifies the Rectifier Module that is the furthest out of balance. The MCA Load Share Alarm can be enabled or disabled by the customer. The factory default setting is to have the MCA Load Share Alarm 'enabled'.

1.4.9 Output Current Walk-In:

(A) Normal Start:

Start up time, defined as beginning at AC switch on and ending when full output power has been reached, consists of two time intervals, the delay period and the output voltage ramp up period.

During the delay period the output voltage will be zero volt. Start up time (AC on, till full power): 5 seconds. Output voltage ramp up period, t: 50 t 150 ms.

(10% to 90% of full power)

The rectifier will not suffer any damage, when subjected to repetitive AC switch on / switch off operations.

(B) Current Walk-In:

90% load in > 8S 100% load max 124s with < 10% time tolerances. According to Telcordia GR-947-CORE, R3-19.

1.4.10 Cooling: Adopting front-to-back force air-cooling.

Thirty-six rectifiers are able to operate in a 400 mm deep cabinet without door, with back panel, 2200 mm high.

The output air from the rectifiers is less than 80C at 55C ambient temperature and 186Vac input 54.5V / 2700W output; and less than 85C at 65C ambient temperature 186Vac input and 54.5V / 2320W output. [EMEA requirement].

The distance is 5mm from the test point to the back panel of the rectifier.

Thirty-six rectifiers are able to operate in a 600 mm deep cabinet without door, with back panel, 2200 mm high.

Fan Control

When input voltage is at normal range, the fans speed is adjusted by the built-in processor according the rectifier's internal temperature.

The fan is turned off when input voltage is abnormal such as very low or high input voltage.

The fan starts at half of full speed when the rectifier starts up.

The fan failure is detected and reported to MCA.

Full fan speed is customer selectable from the MCA.
