Features: This voltage regulator is designed for motor speed regulation and allows adjustment of the output voltage via a precision multi-ring potentiometer. It offers AC 0V-220V continuous adjustability with zero lag and zero delay, providing ultra-high heat dissipation performance. The unit includes anti-surge and anti-peak protection with RC absorption for multiple layers of safety. By connecting the device in series with a lamp or home appliance and rotating the knob, users can control dimming, speed, voltage, and temperature. This item features a new two-way large power silicon controlled rectifier, capable of handling currents up to 100A, making it an effective solution for managing over-current issues in electric stoves during cooling periods. Specifications: - Voltage: AC 220V - Maximum Power: 8000W (instantaneous limit for impedance load; 4000W or lower is recommended for long-term use) - Voltage Regulation: AC 0-220V - Circuit Board: FR-4 circuit board - Max. Current: 100A - Size: Approx. 6*6*4.5cm / 2.4*2.4*1.8 inches - Weight: Approx. 85g / 3oz Use Method: The voltage regulator can be installed in series within the circuit and connected in series with lamps or electrical appliances (either the lamp or appliance can be disconnected from the live or neutral line and connected to the terminal of the device). This setup allows for simple and convenient operation. Package List: - 1 x Voltage Regulator Note: 1. Do not attempt to adjust the voltage before connecting the load. 2. Some professional knowledge is required for safe and proper use.
