Application
4 Tips for Single-phase SCR Power Regulator
- Ensure all power controller wiring terminals are tightly secured to prevent overheating and potential damage to the SCR unit.
- Do not reverse polarity on control terminals relative to COM; improper connection may cause output instability.
- Use within the specified voltage range (180–430V AC) to avoid performance issues or failure.
- 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.
