Silicon Controlled Rectifier (SCR) or Thyristor-based speed regulation. Terminal Connections (Wiring Diagram)
A dedicated integrated circuit (IC) manages the firing angle of the SCRs based on the potentiometer setting. Adjustment Potentiometers (Trimpots): Sets the minimum RPM. Sets the maximum output voltage. Adjusts the "soft start" ramp-up time. jymc220bi schematic full
