Feature:
1. Controller: STM8 industrial control center microcontroller is adopted. Isolate strong and weak current through optocoupler to ensure safe operation.
2. Design: The power line and foot switch line use bolts as quick connection terminals, which is more convenient and reliable.
3 Input time: input time and current adopt high-precision simple potentiometer, which is reliable and convenient for on-board power supply, state, pin, trigger indicator, and working state is clearly visible.
4. Function: reliable zero-crossing detection circuit design ensures SCR phase transfer accuracy. The controller is compatible with 40A scr. The digital control interface can change the current time and current settings.
5. Setting: input time is 1-50, cycle unit (1 cycle is 20 ms), current input (30-99%).
