1. The module adopts the imported silicon controlled rectifier, with the voltage withstand up to 1200V 2. The voltage regulator has a wave peak voltage absorption circuit to effectively protect the high-power SCR for longer life 3. The voltage regulator can adjust the output low voltage through the precise multi turn potentiometer 4. St original imported trigger diode 5. High quality CBB capacitor, withstand DC withstand voltage 630V 6. All potentiometers are equipped with nuts and can be used without any components 7. Module size: 60mm * 48mm * 28mm Input voltage: AC 220V Voltage regulation: 50v-200v Maximum power limit: 2000W Maximum current limit: 25A Note: the module is connected with 220V AC voltage, so pay attention to safety during commissioning Product application Connect the product in series in the circuit of desk lamp or electric appliance, (i.e. disconnect any one of the live line or zero line of desk lamp and electric appliance, and connect the two lines of the "product") rotate the rotary rod of potentiometer, which can play the role of light and shade adjustment, speed regulation, voltage regulation and temperature regulation. It is very convenient to use. The product is applicable to: use the new bidirectional high-power thyristor, the current can reach 25 A It solves the problem of over-current caused by the electric furnace wire, the resistance under the condition of cooling, can easily adjust the output voltage of electricity, can be adjusted arbitrarily between 50-220 volts, can be used by public appliances, such as: the heat regulation of electric furnace and water heater, the light regulation of lamps, the speed regulation of small motor, the temperature regulation of electric soldering iron, etc., so as to achieve the effect of light regulation, temperature regulation and voltage regulation. The power available is less than The 2000 Watt large-scale electric appliance can be used because of its large power, so the general household electric appliance or small factory can be used enough. (the power of inductive or capacitive load should be reduced. The voltage regulator is equipped with two-way high-power SCR potentiometer with nuts, but it can be used with any components, which is very convenient and practical ------------------------------------------------------------------------------------------------------------- Specification: Brand new Material: Semiconductor silicon controlled Size: approx. 85 * 55 * 38 mm Working Voltage: AC 220V Highest power: 4000 watt (connected resistive load, longtime use show lower the power) Under 10amps current, does not need extra cooling. Over 10amps current, need add cooling fan. Voltage regulation: AC 10-input Feature: Control the speed of a AC motor with this controller High temperature resistant FR - 4 circuit board Fine workmanship and stable performance. Durable in use. Used in electric furnace, water heater, lamps, small motor, electric iron etc. Suitable for AC brush motor. How to Use: Adjustable Power Supply Board, connect this device with lamp or home appliance or electric circuit. Then rotate the knob for dimming, speed, voltage, temperature control. ------------------------------------------------------------------------------------------------ Description: The new component assembly4 Terminals,220V into 10-220V adjustable output,Be sure to take the load transferMainly used:Thermostat,Dimming,Governor(Heating pipe, Heating wire ,Heating plate,Heating rods,Baisi bulb,Fan,EAF,Solder furnace,Table lamp) and so on.The regulator be suitable for 220V AC electrical , can be used to dimming, voltage regulator, thermostat, speed and other purposes.
