This AC220V 50Hz 3000W thyristor voltage and speed control module is based on the principle of bidirectional thyristor phase shifting control, which can continuously and steplessly adjust the AC output voltage and achieve four functions of speed control, dimming, temperature control, and power control. The module integrates an RC capacitor absorption circuit to absorb peak voltage and protect components from overheating. With its compact size and simple wiring, it is an ideal module for industrial equipment modification, DIY experiments, and small household appliance power control.

【Important Precautions (Must Include! Reduce After-sales Issues)】

⚠️ Do not exceed 3000W maximum load, as overloading may damage the module

⚠️ Suitable for series-excited motors and resistive loads; cannot be used with frequency converter motors or brushless AC motors

⚠️ For inductive high-power motors, it is recommended to add an absorption circuit to reduce interference

⚠️ This is a high-voltage module. Wiring must be carried out with the power off, ensure proper insulation protection, and pay attention to electrical safety

⚠️ For long-term full-power operation, it is recommended to add a heat sink
