Warm tips: inside the circuit board and capacitor electronic components products can not be used, bedside clip fan miniature fan, small ceiling fans, LED energy-saving lamps, microwave ovens, induction cookers, light wave ovens, washing machines, rice cookers, fish tank pumps, brushless synchronous motors and so on!

Precautions and instructions for use:
1. The output voltage is analog voltage when measuring the mains power, and must be connected to a load of more than 20W in order to measure the correct output voltage.
2. The product input AC voltage, the output is AC, input voltage how much output for the same voltage, not as a boost product use
3.4000W is the limit power of the module in resistive load, with inductive load is 1/3 of resistive load, resistive load refers to tungsten lamps, heating wire, etc., inductive load refers to the string excitation motor, etc., with circuit board electronic products with caution!
4. Resistive load refers to tungsten lamps, heating wire temperature regulation and dimming effect, inductive load refers to the role of motor fan voltage regulator and speed regulator.

Package include:
1 x Electronic voltage regulator 
1 x Power cord
