SCR-1 150A 220V Single-Phase SCR Voltage Regulator

Product Description:
The SoftStarterPro SCR-1 is a single-phase SCR voltage 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. Three LED indicators (POW/OUT/ALM) provide real-time 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: POW (power), OUT (output regulation), ALM (protection)
• 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 Y-150 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.
