Product Description

3kVA~45kVA Variable Frequency Power Supply Units/Frequency Converter/AC Adapter for Home Appliance Manufacturers &amp; Laboratory Testing/ Single Input &amp; Output
INTRODUCTION: 
The variable frequency power supply device (Frequency conversion Power) is a kind of device which is regulating output voltage and variable frequency. Through the inverter control, adjusting the power output, voltage frequency and the load moment of change are key points to adapt the specially working conditions and required protection.

PRINCIPLE: 
Compared with the controller of variable frequency, the variable frequency power supply device is the process of converting AC power from the grid (AC→DC→AC). Then, the output is as a pure sine wave. As the difference between them, the variable frequency power supply device can adjust output frequency and voltage within a certain range. Finally, its power source would be very close to ideal AC power sources. Indeed, the characteristics of an ideal AC power supply are that provides the stable frequency, micro-floating voltage, and zero internal resistance. Certainly, the voltage waveform is a pure sine wave without distortion.
