Variable Frequency Power Supply

Introduction

A frequency converter power supply is a precision power supply that converts utility power into the required voltage and frequency through a power conversion circuit.

Due to the inconsistency of power grid standards across different countries, manufacturers of export products need to simulate various national power grid conditions to test different types of exported electrical equipment. In the past, motor-generator sets were used for secondary frequency conversion; however, they suffered from high power consumption, high noise levels, and poor stability.

The latest frequency converter power supply independently developed by our company can provide standard power grid voltage and frequency for various countries worldwide. The output voltage and frequency are digitally adjustable in a stepless manner. It is suitable for aging tests of export electrical products under different voltage and frequency conditions, and can also be used as a power supply for imported 60Hz equipment.
