Item Type: Voltage Regulator <br>Shell Material: Aluminium Alloy <br>Circuit Board Material: Resin <br>Maximum Load Power: 10000w <br>Efficiency: More Than 90% <br>Working Voltage: AC220V <br>Efficiency: More Than 90% <br>IN Terminal: AC220V <br>OUT Terminal: Electrical Appliances <br>COM Terminal: Public<br>1、Double?sided board design, the pad is not easy to fall off, suits for household and industrial products. <br>2、This voltage regulator has a aluminium alloy shell, so it's safe and convenient to use and install. <br>3、Mainly used for resistive loads, such as electric heating filament incandescent lamps, and so on. <br>4、The 10000W super large voltage regulator can also be used for most single-phase AC motors. <br>5、The circuit board is made of high quality resin material, very durbale for long-term use.1. This product is AC input, AC output, it can only buck when connecting to the load, it is useless to connect a multimeter without load, since it's not a transformer; <br>2. Note that the load must be connected before adjusting the voltage.<p>1 x Voltage Regulator</p><p>1 x Adjusting Knob Cap</p>
