Description: 【Function】: Voltage regulator plays the role of light and shade adjustment, speed regulation, pressure regulation and temperature regulation; it is very convenient to use. 【Applicable】: Voltage regulator use a new type of bidirectional high power , because the current can reach 25 amps, which solves the overcurrent problem caused by too small resistance of the electric furnace wire when it is cooling; it can easily adjust the output of the mains power The voltage can be adjusted arbitrarily between 90-220V for use by electrical appliances. 【Use Voltage】: Voltage regulator AC 220V; Voltage Regulation, AC 50-220V. 【Maximum Power】: Voltage regulator dimmers 2000W. 【Specification 】: Electronic voltage regulator module, High Temperature Resistant FR-4 Circuit Board. Specification: Material: Electronic Components Product Size: 48mmx60mm (Knob Direction) x28mm (Height)   Package Includes: 1 Electronic Voltage Regulator(6 Pack) Note: Please allow slightly errors due to manual measurement and different monitors.
