SCR-1 120A 220V Single-Phase SCR Power Regulator

Product Description:
The SoftStarterPro SCR-1 is a single-phase SCR power regulator for industrial power regulation and heating applications. It supports 4-20mA, 0-5Vdc, 0-10Vdc, 1-5Vdc, and 0-10mA control signals, plus manual potentiometer control, for direct integration with PLC and PID temperature controllers. Using phase-angle control with no mechanical contacts, it delivers fast, stable power adjustment without the wear associated with relays or contactors. Green POWER and red RUN LED indicators provide real-time operating status feedback.

Key Features:

• Control Signal Compatibility: 4-20mA, 0-5Vdc, 0-10Vdc, 1-5Vdc, 0-10mA, 10kΩ manual potentiometer
• Phase-Angle Control: Precise, continuous power regulation
• Semiconductor-Based Switching: No mechanical contacts, fast response, no relay wear
• LED Status Indication: Green POWER indicator, Red RUN indicator (steady or intermittent flashing indicates normal operation)
• CE Certified

General Technical Parameters:

Application:

• Industrial Electric Heaters and Heating Elements
• Ovens and Furnaces
• Plastic and Rubber Heating Equipment
• Packaging and Sealing Machinery

Note: Not recommended for inductive loads (transformers, motors). External heat sink required — use recommended 9225 heat sink with forced-air cooling for this current rating. Test with a small resistive load (e.g. incandescent lamp) before connecting the actual load. Two control modes cannot be used simultaneously.
