Performance-The input power supply voltage is 110V~220V AC. The output voltage is between 50V and 220V (the output voltage is lower tn the input power supply voltage). The maximum output power is 2000W. The maximum output current is 25 Multiple Operations-Our speed controller can be used for electric cooker, water heater heating, lighting dimming, low speed motor, electric iron temperature adjustment. Achieve the effects of dimming, temperature adjustment and pressure adjustment. Application-Our products can be used for large electrical appliances with a power of less tn 2000 watts. Due to the high power, large household appliances or small factories are sufficient. Selected materials - using the new high-power bidirectional thyristor, the current can reach 25 amps, which solves the overcurrent problem caused by the low resistance of the electric oven wire during cooling. Specifications - Module size: 1.85 1.38 1.06 inches (without buttons). Button diameter: 0.79 inches. Net weight: 1.76 ounces. Product description Usage: Connect this product in series in the circuit of the desk lamp or electrical appliance (tt is, disconnect the lamp or electrical appliance from one of the live or neutral wires and connect the two wires 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.
