Detailed Product Description：	Safety Test: Safety testing is focused on CE certification testing is testing problems, testing more content, require safety requirements and standards for almost GB 4943, the test as follows: 1. nameplate, label permanently Test: Test Method: cloth dampened with soapy water or gasoline wipe 15 seconds and then check the nameplate label, label situation. Criteria: nameplates, labels do not come off, you can not roll angle, clear handwriting. 2. Enter the current test: Test Method: City under the maximum input current test prototype electric mode, should test at full load and low overloading. Criteria: Requires no more than 110% of the nominal value of the input current. Time oscilloscope with a high voltage probe test voltage capacitors, the highest peak of the input voltage when the input voltage is disconnected, with an oscilloscope to measure the voltage dropped from the highest safe voltage value at the time: 3. The main circuit capacitor discharge test: Test methods , if there is a power failure can be set to a fixed phase AC SOURCE best, if not, can only be repeated several times until a power phase is 90 degrees or 270 degrees. Criteria: In a time of constant inner (<1s), the voltage should be reduced to below 37% of the input voltage. Note: X capacitance value
