Electronic Voltage Regulator 220v 4000w Stepless Adjustable High Power Heating Temperature Regulation Speed Controller

Description

Zero hysteresis, zero delay, with peak voltage absorption circuit to effectively protect high-power thyristor, anti-surge, anti-peak, RC absorption multiple protection. The measured output voltage when the machine is empty is a virtual voltage, and the correct output voltage must be connected to a load of more than 20W. Input alternating current, the output is also alternating current. The shell of the product is made of PC/PP flame retardant material.
