  • Product Description

  • Product Introduction

    Variable frequency power supply is a kind of power control device, so as to meet the needs of users. Variable frequency power supply can not only simulate the output of different national power grid indicators, but also for export electrical manufacturers in the design and development, production, testing and other applications to provide pure and reliable, low harmonic distortion, high stability of the voltage and frequency of the sine wave power output. The sine wave pulse width modulation (SPWM) variable frequency power supply, which is composed of AC current AC (modulation wave) and other circuits, is controlled by this variable frequency technology in most small and medium-sized variable frequency power supplies. The variable frequency power supply has the advantages of obvious energy saving effect, wide adjustment range, low noise, high reliability, simple maintenance and so on.

    This variable frequency power supply takes microprocessor as the core, is made in PWM mode, and is designed with active element IGBT module. It adopts digital frequency division, D/A conversion, instantaneous value feedback, sinusoidal pulse width modulation, feedback control, display unit, logic control, protection circuit and other technologies. It has strong load adaptability, good output waveform quality, simple operation, small volume, light weight and other characteristics. It has short circuit, overcurrent, overload and overheating, overvoltage and other protection functions to ensure reliable operation of the power supply.
