Thyristor Power Regulators for Resistive Load

Thyristor Power Regulators for Resistive and Inductive loads

Libratherm offers ready to use SCR power controller for electrical heating loads ranging from 3 KW/Single phase to 360KW/3-phase. This power controller 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 copper bus bars, semiconductor fuses and thermal cutouts. The entire assembly is mounted on MS powder coated enclosure, 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.

BrandLIBRATHERM
ModelPOW-1-PA

Features:
  • 5 Amps to 460 Amps capacity (2KW to 573KW).
  • Single phase / 2 phase / 3 phase versions.
  • Suitable for 3 or 4 wire star configuration / 3 or 6 wire delta configurations.
  • Auto / Manual operation.
  • Accepts (4-20)mA / (0-5)VDC / (0-10)VDC control input (user selectable)
  • Soft start and step less smooth control.
  • Adjustable current control and over load trip feature.
  • Isolated heat sink for safety.
  • Simple and Modular design for easy servicing of firing cards and thyristors.
  • Ideally suitable for resistive, transformer, inductive or heating loads like Silicone Carbide and Molybdenum which exhibits significant changes of resistance with increase in temperature.
Applications:

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 savings with respect to conventional contactor type temperature control system. Thyristors have many direct and indirect advantages compared to electro - mechanical contactor.

Applications:
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 savings with respect to conventional contactor type temperature control system. Thyristors have many direct and indirect advantages compared to electro - mechanical contactor.
