Sedecal Group

Sedecal Control, S.A. was founded in March 1995.The Company was intended for designing andmanufacturing of medium and high power softstarters, frequency converters and power systems fordifferent applications in the field of heavy industry.

Sedecal Control is located in Algete (Madrid), and itis part of Sedecal Group.

Soft Starter Concept• On the squirrel cage motors, the start up current can

be up to 5 - 10 IN.

• The start up current is proportional to the appliedvoltage.

• 50 % of applied voltage leads to 50% and 25% ofcurrent and torque respectively.

• The start up time is a function of the motor - machineinertial characteristics. (Big fans need about 60seconds, and pumps 20 seconds approximately).

Industries• Paper mill Pulpers, refinders, pumps and fans• Steel mill Big fans, compressors, pumps and fans• Petrol Big fans, compressors, pumps and fans• Chemistry Fermentation stations, compressors,

pumps and fans• Water Desalination stations, compressors, pumps

AdvantagesSAP 600 and SAP 6000 soft starter controllersensure the “soft” starting and stopping of largethree-phase induction motors without excessivepeak currents, motor heating or mechanicalshocks.

This has a particular importance in large machi-nes due to the power consumption in themegawatt range. The energy adsorbed by themotor winding and the shock torque have bothand important impact in the mechanical partsand consequently, influences the equipment life-time.

SAP 600 and SAP 6000 allow the reduction ofcable section and the energy peak power fromthe electricity supplier.

SAP 600 and SAP 6000 compensate the voltagedrop on the power cables. The soft startercontrollers apply the pre-set current values.

SAP 600 and SAP 6000 use current control. Thepre-set current value is not affected by the linevoltage or the specific motor start-up currents.

The power and control circuits are communica-ted through optical fibre.
