2000W 220V SCR Voltage Regulator Dimmers Speed Controller Thermostat

Prototyping and Engineering Tips from Robogears

• The "Inductive Load" Rule: While rated for 2000W with resistive loads (like a heater), you should significantly de-rate the module when using inductive loads (like motors). For AC motors, we recommend not exceeding 500W–800W to account for high start-up currents and back-EMF.

• Not for Brushless/Capacitor Motors: This regulator will not work with brushless AC motors, induction motors (like ceiling fans), or devices with electronic start-up circuits. Using it on these may result in a loud hum or motor failure.

• Lethal Voltage Warning: CRITICAL: This entire module is "Hot" when plugged in. There is no galvanic isolation between the control circuit and the 220V AC mains. Never touch any part of the PCB, heatsink, or potentiometer shaft while the unit is connected to power. Always mount this inside a non-conductive plastic or earthed metal enclosure.

• Minimum Load: Some SCR regulators require a minimum load (usually 10W–20W) to show a voltage change on a multimeter. If you measure the output without a load connected, you might see 220V regardless of the knob position.

• Thermal Monitoring: If the heatsink becomes too hot to touch (above 70°C) during operation, you are likely overloading the module or need to add an external cooling fan to the enclosure.
