Product Description

<p style="text-align:center;"> VFP-H Series High Frequency AC Power Supply


Variable frequency AC power supply converts AC electric to pure sine waveform by through AC – DC – AC conversion, which is different from variable frequency speed controller and common AC voltage regulator.

Variable frequency power supply is mainly used to convert existing AC power network supply to stable and pure sine power supply with regulated required frequency. The features of ideal AC power supply are stable frequency, stable voltage, zero internal resistance and Sine wave form (without distortion). Variable frequency power supply is close to the ideal AC power supply, so the developed countries more frequently use variable frequency power supply as the standard supply to provide the most excellent powering environment for electrical equipment and to easily evaluate their technical performance. Major types of variable frequency power supply are: Linear Amplification and PWM Switching

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.2kva High Frequency Ac Power Supply Front View
