Huayi Power is a professional manufacturer specializing in the research and development of portable voltage testers. Huayi Power's portable voltage testers are widely praised in the industry and strive to create the most authoritative "portable voltage tester" high-voltage equipment supplier. Huayi Power's portable voltage tester is a measuring instrument for testing the voltage resistance performance of electronic components, wires and cables, and electronic equipment. It is suitable for testing the safe voltage resistance and leakage current of various motors, appliances, instruments, household appliances, and high-voltage systems.

The AC test voltage of the portable voltage tester is generated by a step-up transformer, and the voltage adjustment is achieved by a voltage regulator. After voltage division and rectification, the output voltage is sent to the voltmeter for indication. The test current is first sampled by a resistor and then rectified into the corresponding voltage through a diode. One path is sent to the ammeter for indication, and the other path is sent to the microprocessor through an A/D converter for comparison with the leakage current setting value, thereby achieving overcurrent alarm control. The portable withstand voltage tester is suitable for testing the safe withstand voltage and leakage current of various motors, appliances, instruments, household appliances, as well as high-voltage systems. This instrument is easy to operate, safe and reliable, with good performance and easy maintenance. It is a testing equipment that meets the testing requirements of GB4706.1 "General Requirements for Safety of Household and Similar Electrical Appliances" and GB9706.1 "General Requirements for Safety of Medical Electrical Appliances", as well as relevant clauses in national standards such as GB4943 and GB4793.
