POW-1-PA-CL – Single Phase SCR Power Regulator for Single Phase Heater with Current Control/Current Limit and Over Load Protection.

Key Features:

  • Digital Firing Cards for single-phase/two phase/three phase are Field-proven for 25+ years.
  • Semikron make SCR Modules – SKKT Series are used for AC to AC control and SKKT / SKKH Series are used for AC to DC control.
  • Auto-detection of phase sequence and auto-synchronization.
  • Heatsinks are mounted with thermistors to protect against overheating and auto cut-off of firing in case of over temperature.
  • Built-in Current Limit and Overcurrent Trip facility to limit the desired current through heaters. This feature saves on the cost of using external safety fuses.
  • Soft start and Soft stop voltage across the load.
  • Separate auxiliary supply of 230 VAC with built-in RFI/EMI filter – Thereby electronics are safe against line voltage fluctuations and RFI/EMI electrical noise.
  • SCR Modules are protected by suitable RC snubber and surge suppressors.
  • High-speed ball bearing type cooling fan – To keep Thyristor cool.
  • Built-in safety fuse for the cooling fan and Auxiliary supply.
  • Current control feature avoids the need for external Fuse in series with the load.
  • Rugged metal enclosure & modular design – easy to install & easy to maintain.
  • Libratherm Thyristors are time tested & field-proven in all major industries for the last 25+ years.

Current RatingSingle Phase SCR power regulator for 2KW @ 230VAC heater load (DIN rail mount)
Mounting Type35 mm. DIN rail or base plate mounting.
Enable or Disable inputEnable

Libratherm offers a Single Phase Thyristor Power Controller for heating control of resistive or inductive loads. This phase angle controlled SCR Power Regulator accepts the user-selectable control signal of 0-5V, 0-10V, and 4-20mA or through the potentiometer, and hence, can be easily interfaced with DDC, PID, or PLC. The output voltage can be varied proportional to the input signal. The phase angle firing control technique ensures a smooth and gradual step-less voltage control across the heater load. The facility is also provided to adjust the soft rise or drop in the voltage across the load using on card Ramp Up and Ramp Down potentiometers. The maximum and minimum voltage output can also be adjusted. These Thyristor Power Pack Modules can be easily mounted on the standard 35mm DIN rail or on the base plate using 4 screws.
