What is a variable frequency power supply? Frequency conversion power supply is the AC power in the city through the AC - DC - AC transform, the output of a pure sine wave, the output frequency and voltage within a certain range can be adjusted. It is different from the use of motor speed control of the variable frequency speed controller, but also different from the ordinary AC regulated power supply. The characteristics of the ideal AC power frequency stability, voltage stability, resistance equal to zero, the voltage waveform is a pure sine wave (distortion free).

Frequency conversion power daily check items? Variable frequency power supply on power before should first check the surrounding environment temperature and humidity, temperature is too high will lead to variable frequency power supply overheat alarm, serious will directly lead to variable frequency power supply device damage, short circuit; air is too humid will lead to variable frequency power supply direct internal short circuit
