AC 220V 4000W High Power SCR Electronic Voltage Regulator Speed Controller Thermostat with Fan

Parameter: Operating voltage: 110V-220V AC; Maximum power: 4000W (connected to a resistive load); Voltage regulation: adjustable between AC input voltage and 0; Size: 91mm x 59mm (without handle), 34mm total height; Model: ZS-PA4000A; Instructions for use: Connect the input of this product to 220V AC, and connect the output to the wire of the electric oven or electrical appliance, and rotate the potentiometer to adjust the speed, voltage, and temperature; it is very convenient to use. This product is suitable for: using a new type of high-power bidirectional thyristor, as the maximum design current can reach 20A, it solves the overcurrent problem caused by insufficient resistance of the electric oven wire when it is cooling; It can be easily adjusted. The mains output voltage can be arbitrarily set between 0 and 220 volts for electrical appliances such as electric furnaces, water heaters, lamps, small motors, and electric irons. This allows for dimming, temperature control, and pressure regulation. It can be used for large electrical appliances with a power consumption of less than 4000W. Since the power output is already significant, it is sufficient for general household appliances or small factories. (The power of the inductive or capacitive load must be reduced. The voltage regulator is equipped with a high-power bidirectional thyristor; the potentiometers are all equipped with nuts and feature a thick aluminum casing and a large heatsink. It can be used without adding any components. Convenient and practical.) Precautions: Note that the load cannot exceed the specified maximum power, otherwise the modules and electrical devices will be burned out; try to use resistive loads; the power of inductive and capacitive loads must be significantly reduced (it is best to leave at least half the load).
