Product Description

Product name

EDS1000 series multi-function universal frequency inverter (VFD/variable frequency drive/AC drive)


Power Range

Single-phase AC 220V±15% 0.4-3.7KW

Three-phase AC 380V±15% 0.75-55KW

Three-phase AC 690V±15% 11-200KW



EDS1000 series Multi-function universal frequency inverter has 150% rated torque at 1 Hz, meeting the requirement of low noise, high torque, low electromagnetic interference and covering three voltage grades: 220V, 380V and 690V. This kind of frequency inverter is widely used in applications which require high-speed control accuracy, rapid torque response, and high performance at low frequencies.


Technical Features of frequency inverter

  • Infineon IGBT module (German brand) adopted, featuring less failure rate and smaller size compared with single-transistor inverter.
  • Fujitsu CPU (Japanese brand) adopted, characterizing rapid and stable calculation.
  • Mini size, suitable for all kinds of applications
  • Abundant DI/DO and AI/DO
  • 150% rated torque at 1 Hz frequency
  • Built-in PID controller, realizing constant pressure (flux etc.) "One inverter drives multiple devices" control (optional function)
  • 16 (maximum) section speed control
  • 0-20KHz pulse input output interface
  • Spinning traverse function
  • Automatic voltage regulation (AVR) and automatic current limiting function
  • RS485 communication interface (optional part)
  • Multi-frequency input channel selection
  • Closed-loop running control
  • Keypad parameter copy function and password protection function
  • Crystal English display keypad and English operation content indicating.



  • Textiles, plastics, blower, pump, ceramics, electronics, numerical controls, foods processing, weaving, transportation machine, metallurgy machine,  constant pressure water supply, air compressor, air conditioner, music fountain, paper making, chemical mechinery etc.
