Performance-The input power supply voltage is 110V ~ 220V AC. The output voltage is between 50V and 220V (the output voltage is lower than the input supply voltage). The maximum output power is 2000 W. The maximum output current is 25 Multiple operations - Our speed controller can be used for electric stove, water heater heating, lighting intensity reduction, low speed motor, electric iron temperature adjustment . Get dimming, temperature setting and pressure setting effects. Application-Our products can be used for large electrical appliances with power below 2000 watts. Due to the high power, large household appliances or small factories are sufficient. Selected materials - thanks to the new high power bidirectional thyristor, the current can reach 25 amps, which solves the problem of overcurrent caused by the low resistance of the electric furnace wire when cooling. Specifications - Module size: 1.85 1.38 1.06 inch (without buttons). Button Diameter: 0.79 inch. Net weight: 1.76 ounces. Product description Usage: Connect this product in series into the desk lamp or electrical appliance circuit (that is, disconnect the lamp or electrical appliance from one of the live or neutral wires and connect both son of the " product ". The rotating rod of the rotary potentiometer can play the role of brightness adjustment, speed regulation, pressure regulation and temperature adjustment; it is very convenient to use.
