Overview

The HTBP series variable frequency power supply is a precision power supply that converts mains electricity into the required voltage and frequency through a power conversion circuit. Our company's independently developed high-performance variable frequency power supply can design and output various voltages and frequencies according to the needs of different users to meet the power supply and testing needs of electrical products in different countries and regions. Variable frequency power supply can also be used as a power supply for imported 60Hz equipment, and can convert single-phase 220V power supply to three-phase 380V power supply. It is also suitable for converting three-phase 220V (60Hz) to three-phase 380V (50Hz) or inputting three-phase 380V (35-70Hz) and outputting 380V (50Hz) power supply.

Product Features

The variable frequency power supply adopts sine pulse width modulation PWM design and imported 1GBT drive. The circuit composition mainly consists of input rectification and filtering circuit, high-performance frequency converter, isolation transformer, output filtering circuit, PID control regulation and other units. It has the characteristics of high stability, strong overload capacity, large power capacity, good output waveform, simple operation, etc.
