POW-1-PA-CL – Single Phase SCR Power Regulator for Single Phase Heater with Current Control/Current Limit and Over Load Protection.
Libratherm offers ready to use SCR Power Controller for electrical heating loads ranging from 5 KW (Single Phase) to 360KW (Three Phase). This Thyristor Power Regulator Module comprises of suitable triggering card model LTC-12 or LTC-13 or LTC-15 or LTC-18, suitably rated back to back connected SCR Modules (with electrically isolated base, mounted on the heat sink, input and output clip-on type heavy-duty connectors or aluminum/copper bus bars, semiconductor fuses and thermal cutouts. The entire assembly is mounted on an MS powder-coated enclosure, which in turn can be easily mounted inside the closed control panel as desired. A complete ready-to-use phase angle controlled control panel with a suitable PID / Program Temperature Controller can also be supplied as per the user’s specifications and requirements. For DC rectified output the assembly remains the same, except the SCRs are connected in Bridge Configurations.
Thyristor Power Controller has a varied application and can be used with heating elements like Nichrome, Canthal, Super Canthal, Silicon Carbide, Molybdenum, Infra-Red, step up or step down transformer, etc. where precise and accurate power and temperature control is required. There is a significant electrical power saving with respect to the conventional contactor type temperature control system. Thyristors have many direct and indirect advantages compared to electromechanical contactors. Ideally suitable for resistive, transformer, inductive, or heating loads like Silicon Carbide and Molybdenum which exhibits significant changes of resistance with an increase in temperature.
