AC 220V 2000W SCR Voltage Regulator Dimming Dimmers Motor Speed Controller Thermostat Electronic Voltage Regulator Module This regulator is specially improved for motor speed control circuit can be adjusted by precision multi-turn potentiometer output low voltage. Parameters: Use voltage: AC 220V Power: 2000W Voltage regulation: AC 50-220V Size: high temperature FR-4 circuit board circuit board 36MM * 48MM or so External dimensions: 48MM * 60MM (knob direction) * 28MM (high) Silicon control voltage up to 1200V / current 25A 1.6mm thickened epoxy copper-clad plate The regulator with peak voltage absorption circuit to effectively protect the high-power SCR, longer life and more durable. Usage: This product is connected in series in the lamp or appliance circuit, (i.e., the lamp, appliances, etc., disconnect any one of the firewire or zero line, the ""product"" of the two wires can be connected) rotate the potentiometer lever, you can play the role of light and dark regulation, speed, voltage, temperature; very convenient to use. This product is suitable for: the use of new two-way high-power silicon controlled, because the current up to 25 amps, a good solution to the electric stove wire in the case of cooling resistance is too small, thus causing the overcurrent problem; can easily adjust the output voltage of the utility, in the 90 ---- 220 volts arbitrarily adjusted for the use of electrical appliances. Such as: electric stove, water heater heat, lamps and lanterns dimming, small motor speed, soldering iron temperature. So as to achieve the effect of dimming, temperature regulation, voltage regulation. Can be used for power consumption less than 2000 watts of large electrical appliances due to the power has been very large, so the general family appliances or small factories enough to use. (Inductive or capacitive load power should be reduced, the regulator is equipped with a bidirectional high-power silicon controlled, potentiometer with a nut, without adding any components can be used, very convenient and practical).
