Thyristor Power Controllers For Resistance Heaters & Transformer Loads

Libratherm offers ready to use SCR power controller for electrical heating loads ranging from 3 kW/single phase to 300 kW/3-phase. This power pack module comprises of suitable triggering card model LTC-12 or LTC-13 or LTC-15, suitably rated, and with a back-to-back connected SCR module (with electrically isolated base), mounted on the appropriately rated heat sink (natural air or forced air cool). The SCR power controller comes with input and output clip-on type heavy duty connectors or copper bus bars, semiconductor fuses and thermal cutouts. The entire assembly is mounted on MS powder coated plate, which in turn can be easily mounted inside the closed control panel as desired. Complete ready to use control panel with suitable PID/Program temperature controller can also be supplied as per the user’s specifications and requirement. Thyristor Power Pack has a varied application and can be used with heating elements like kanthal, super kanthal, silicon carbide, molybdenum, infra-red, etc., where precise and accurate power control is required. There is significant power savings with respect to conventional contactor type temperature control system, which also depends on various other factors. The company also offers SCR Triggering Cards for Phase Angle Control, Microprocessor Based Sixteen Channel Data Logger, Microcontroller Based Temperature/Process Scanner, Data Acquisition Software, Multi Loop PID Controller, etc.
