Application

4 Tips for Single-phase SCR Power Regulator

1. Ensure all power controller wiring terminals are tightly secured to prevent overheating and potential damage to the SCR unit.
2. Do not reverse polarity on control terminals relative to COM; improper connection may cause output instability.
3. Use within the specified voltage range (180–430V AC) to avoid performance issues or failure.
4. For control signals, note that the adjustable range is typically between 4.5mA and 18mA, with lower and higher ranges acting as off and full-on zones, respectively.
