The output is recommended not to short circuit, you must first connect the load, and then adjust the voltage!
Natural heat dissipation is recommended to work for a long time within 2000W, more than please strengthen the heat dissipation!
Specifications: Product name: 4000W AC voltage regulator
Size: length 85 * width 55 * height 38mm, knob inner hole 6mm. Maximum power: 4000W (resistive load limit power), power should be reduced for a long time. It is recommended that the long-term resistive load is within 2000. Efficiency: more than 90%.
Operating voltage: AC 220V Adjustable voltage: AC 0-220V (from high to low can be to 0, from low to high is about 10V) The binding post 1 is connected to the input 220V, and the binding post 34 is connected to the load. Note: The load must be connected before the voltage is regulated.
