Project Description

  • LW-500W Front View

This variable frequency power supply uses a microcomputer processing chip and high-power devices. It provides stable and pure sine waves, and provides overvoltage, overcurrent, overtemperature, and overload protection. The output voltage is continuously adjustable from 0 to 300V, and the frequency is continuously from 45 to 70 Adjustable or fixed frequency 50Hz, 60Hz, 100Hz, 200Hz, 400Hz, can simulate the power grid conditions in different countries, provide stable voltage, frequency, waveform to meet the testing and aging of export products, and provide laboratories, measurement rooms, etc. Do various precision tests.
