ABB's pF-TSM is a Thyristor Switch specifically designed for high speed switching of Power Factor Correction Capacitor Banks. (10kVAr, 25kVAr & 50kVAr @ 415/ 440VAC, 50Hz). Triggering of Thyristor Switch is done by Power Factor Controller meant for such applications viz., ABB-RVT-D / ABB-PFR-T12 etc. having a Transistor Output for the said purpose. It can also be triggered by other means using PLCs & Solid State Relays as well. Thyristor switching module is for high speed Reactive Power Compensation Systems in Low Voltage grids from 415 / 440 V, 50 Hz, using single or multiple components of 50kVAr, 25kVAr & 10kVAr.
  • Suitable for capacitor units with or without detuning reactor.
  • High speed switching at Zero differential voltages
  • Self Cooled Units with Option of Forced Cooling.
  • Monitoring of Supply Voltage, Input Trigger and Thermal Fault.
  • ABB pf-TSM Datasheet V1, 31st Jul18No external Power required for TSM.
  • Optional cooling FAN runs on external power 230VAC, 50Hz.
  • Optional Annunciation Extension Unit using potential free contacts 30VDC, 1A or
  • 230VAC, 1A.
  • Robust connections via Copper Bus-bars with safety cover.
  • Rodent entry protection.
  • Extreme Climate Condition compliant.
  • ROHS Compliant.
  • No Eddy Current Cable Heating.
  • IP Protection Class: IP20.
  • Least maintenance.
  • Lowest TCO.

Application Examples:
High Speed Reactive Power Compensation is desired in applications where the Power Factor changes are very rapid, viz.,
  • Welding Equipments.
  • Wind Turbines.
  • Fast Operation presses.
  • Elevators.
  • Cranes.
  • Others.

TSM Mounting & Connection Information:
  • The Thyristor Switch is mounted directly on the Component Mounting Plate of the Low Voltage Switchboard / Panel. Clearance of 150mm is required for ventilation. The
  • Power Supply connections are made using copper flexible cables appropriately sized, through protective devices (viz. high speed fuses) as mandated.
  • A 12 VDC - 24 VDC trigger signal coming from the Power Factor Controller or other arrangement is to be connected at points “T+ & T-”, for triggering ON the module. It is possible to trigger multiple Thyristor Switch Modules simultaneously to achieve a larger kvar step capacity.
