A bi-directional high-power thyristor is used, supporting up to 25 A current, helping prevent over-current issues that may occur during cooling when electric furnace wire resistance is low. The device allows easy adjustment of output voltage between 50 V and 220 V AC, making it suitable for various electrical equipment with different voltage requirements. It is primarily designed for resistive loads (e.g., incandescent lamps). Some single-phase AC motors may also be compatible, though compatibility is not guaranteed. Suitable for controlling lamps, fans, motors, and similar devices. Maximum resistive load power: 2000 W. For continuous operation, it is recommended to limit the resistive load to under 1000 W at room temperature (key parameter — please note).
