The Active Front End unit ensures energy saving and power quality providing devices such as inverter and servo-drives (from any brand) with energy without fluctuations and current peaks thanks to PWM modulation.

Energy usually wasted heating resistors is supplied back to the mains.
Very effective in applications with vertical loads or big inertia brakings, AFE2000 can share the DC-BUS with many devices bringing back the power factor close to 100%.

Main features:

  • Energy saving with bidirectional power exchange between devices and mains
  • Replaces traditional braking resistor converting dissipated energy into reusable power
  • Ensures stable DC-BUS filtering mains fluctuations
  • Lowers THD and raises power factor up to 99%
  • Built-in MODBUS RS485, many fieldbus available with optional cards
