VFP-H series variable frequency power supply is manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation.
Comparing to traditional frequency inverter power supply, our inverter power supply removes the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC inverter power supply could give stable AC output with prefect output precision.
Because, our new technology does not need transformer for conversion and isolation, the power supply size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
