Overview

The ME800 MV Industrial Drive from STEP is a high-voltage source type drive integrating power electronic and vector control technology. It offers power ranges from 250kW to 12500kW across voltage levels of 3kV to 11kV. Features include multi-level PWM control, low harmonic distortion (THD <5%), and support for asynchronous and synchronous motors. It has a touchscreen interface, IP30 protection, and forced air cooling. Applications span power, steel, chemical, cement, rubber, sugar, and other industries.

Key features

  • ▸Multi-level PWM control mode, providing sine wave current output
  • ▸Low common mode voltage and du/dt, no special requirement for the motor and cable
  • ▸Multi-pulse rectifier effectively suppresses higher harmonics, THD <5%
  • ▸Drives asynchronous motor and synchronous motor (permanent magnet synchronous and other excitation synchronous)
  • ▸Main control chip integrates ARM core processor; power unit control via large FPGA programming chip
  • ▸Main control board directly communicates with IO board for DI/DO and AI/AO functions, no PLC needed
  • ▸User interface with touchscreen
  • ▸Protection: overvoltage, undervoltage, overcurrent, short circuit, overheating, power unit failure
  • ▸Communication: Standard Modbus; Optional Profibus-DP
  • ▸Transformer insulation class H
