Product Name: Electronic Voltage GovernorModel: ST-BTA-BInput voltage: AC220VOutput voltage: AC0-220V constantly adjustableRated current: 15ARated power: resistive 2000W inductive 1500WZero hysteresis, 0 delay, and height voltage absorption circuit efficiently preserve high-power thyristorsProduct features: anti-surge, anti-spike, RC absorption several protectionPurchasing noticePrecautions and instructions for use1. The measured output voltage is an analog voltage when the mains is powered, and the right output voltage can fully be measured when a load of more than 20W is connected. The product enter AC voltage, the output is AC current, the enter voltage is an identical voltage, not when the boost product makes use of 3 for the ultimate strength of the module in the resistive load, the inductive load is third of the resistive load, the resistive load refers to the tungsten lamp, heating wire, etc., the inductive load refers to the sequence motor, etc., and the electronic merchandise of the circuit board are used with caution. The resistive load refers to the tungsten lamp, the heating wire temperature and light-weight regulation, and the inductive load refers to the voltage and speed legislation of the motor fan protection switchIn case of overload or short circuit, the overload replace works to disconnect the output, and mechanically restores the output after troubleshooting, without replacing the fuse, security is as clear-cut as that! It isn't just a switch, but additionally an overload protector
