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

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.
