Description: Working voltage: AC 220V Regulation voltage: AC 10-220V Max power: 4000W (resistive load) Efficiency: 90% Dimensions: 85 x 55 x 38MM   Note: You must connect to the load before the regulator. SCR is mainly used for resistive loads (incandescent electric wire, etc.) Most of the single-phase AC motor can, but can not guarantee, other types of loads buyer to confirm their own.
