50-1,200 amp, -48 VDC Vortex® PowerSystem with 50 or 65 amp PCUsDescription

The Vortex power platform with 50 or 65 amp power conversion units (PCUs) is amodular power system providing up to 1,200 amps of power for -48 volt systems. Thebasic components of a Vortex power system include an intelligence shelf, which houses themeter–control–alarm microprocessor (MCA) and PCUs; expansion shelves for additionalPCUs; and a modular distribution cabinet.

The intelligence shelf can accommodate up to four PCUs, and the expansion shelves, alsohousing up to four PCUs each, can be added for larger load requirements. The intelligenceand expansion shelves are 23" (58.42cm) wide x 10.5" (26.67cm) high.

In addition to housing the PCUs, the intelligence shelf provides a powerful,microprocessor-based meter–control–alarm system which is capable of monitoring andcontrolling up to 56 PCUs. The front of the intelligence shelf provides a 16-characteralphanumeric display which can be activated at the touch of a keypad.

Vortex distribution is modular by row and position. The cabinet allows for up to four rowswith a maximum of 96 positions. Users can combine any number of 1–150 amp circuitbreakers and 1–50 amp TPA-style fuses to customize power plants. GJ-style circuitbreakers and TPL-style fuses are also available.

Application

The Vortex system, powered with 50 or 65 ampPCUs, is ideal for wireline and wireless applicationssuch as switch sites, remote cabinets, CEV and UEsites, customer premises and cell sites.

The Vortex platform includes a modular distribution product line that can be designed with one to four panels. Eachmodular panel can be configured with any combination of distribution positions, low voltage disconnect and batterydisconnect. Distribution cabinets are front accessible, modular in design and are initially configured in the factory.The cabinets are 24.375" (58.42cm) wide, 17.5” (44.45cm) deep andvary in height depending on the capacity. Circuit breakers and/orfuse modules snap into the multi-position distribution blocks toprovide for easy installation. For larger device requirements, TPL-style fuses and GJ-style breakers are available up to 600 amp ratings.

Intelligence Shelf

A front access intelligence shelf houses up to four PCUs. Availableshelf ratings are 200 amps (with 50 amp PCUs) or 260 amps (with65 amp PCUs). The intelligence shelf includes the MCA, whichprovides a single point of adjustment for such features as floatvoltage, test/equalize voltage, high voltage shutdown and currentlimit adjustments for all PCUs in the entire power system. Theintelligence shelf allows users to view specific alarm conditions,system measurements and system settings. All adjustments can beperformed locally via the alphanumeric display panel on the frontof the intelligence shelf or remotely via optional software andhardware. The MCA provides local indicators and the ability totransmit various alarm conditions such as PCU failure, highvoltage shutdown and AC failure.

A standard 7’ high power system can contain one to fourfront-access expansion shelves, each of which houses up tofour PCUs. Available shelf ratings are 200 amp (with 50amp PCUs) and 260 amp (with 65 amp PCUs). Theexpansion shelves are 23" (58.42cm) wide, 10.5" (26.67cm)high and 14.88" (37.78cm) deep.

Power Conversion Units

The modular, high frequency, switch-mode Vortex PCUsare the foundation of the Vortex platform. Plug’n’play technology allows for easy system configuration. System capacity canbe increased by simply plugging an additional PCU into an existing intelligence or expansion shelf — no adjustments orsetup is required. The Vortex power system can house up to 20 PCUs which provide load power, battery float current andbattery recharge current. The PCUs are monitored and controlled by the intelligence shelf. The PCUs allow the user toappropriately size a power plant (50 to 1,200 amps) to meet specific applications.

Power Conversion Unit Specifications

InputVoltage: Nominal 208/240 volts AC, single phase, 50/60 Hz,with a range of 176 to 264 volts. Extended range is 150 voltsAC to 290 volts AC (50 amp unit only).Inrush Current: Peak does not exceed 2 times the RMSinput at full load, under any conditions of input voltagewithin the rated input voltage range.Frequency: 45–70 HzProtection: Each PCU is individually wired andconnections for individual AC input branch circuits areprovided. If the AC input voltage decreases or increasesbeyond a non-adjustable predetermined value, the PCUpower conversion circuitry inhibits, disabling PCU output.The PCU will recover automatically when the AC inputvoltage is re-established within specifications limits.Typical Power Factor: Greater than or equal to 98% for anyload greater than or equal to 50% of rated full load atnominal line. Meets IEC 1000–3–2.Typical Operating Efficiency: 90% at full load.

OutputVoltage: Nominal -48 volts DC, Positive Ground.Current: 50 amps per PCU, up to a total of 200 amps pershelf with four PCUs installed. 65 amps per PCU, up to atotal of 260 amps per shelf with four PCUs installed.Regulation: Steady state output voltage remains within±0.5% of any voltage within the range of 44.0 to 58.0 voltsDC (44.0 to 57.0 volts DC for 65 amp PCUs) for anycombination of frequency, normal input voltage, and loadfrom no load to full load over the temperature range of-20° C to +65° C (-4° F to +149° F) for 50 amp PCUs, -20°C to +50° C (-4° F to +122° F) for 65 amp PCUs.Filtering: On or off batteryVoice Band Noise — Less than 32 dBrndCWide Band Noise — Does not exceed 500 mv peak-to-peak,or 30 mv rmsPsophometric Noise — Does not exceed 1 mv
