Frenic 4600

"Medium Voltage AC drive from FUJI.."

The Fuji Electric medium-voltage IGBT inverter FRENIC4600FM5e is used for direct variable-speed control of medium-voltage motors. It greatly raises the efficiency and power factor, stabilizes motor operations and conserves energy.
  • Compact design for space saving:
    One of the industry’s smallest-class inverters, achieved by significant panel size reduction.
  • Ideal inverter for power sources and motors:
    The multi-phase diode rectifier system reduces harmonics on the power source side. Due to the use of Fuji Electric’s unique multi-level PWM control system, the switching surge is reduced and existing motors (standard ones) can be operated.
  • High-efficiency and high-power factor:
    The use of a multi-phase diode, full-wave rectifier provides a high-power factor (95% or more) on the power source. The elimination of output transformers for operation has improved total efficiency (approx. 97%). Fuji Electric’s original multi-level PWM control has reduced the IGBT switching loss.
  • High-reliability:
    Higher equipment reliability is achieved by reducing the number of inverter cells by using a single-phase, 3-level inverter, etc.. Stable operation is maintained despite load fluctuations, by the simple sensor-less vector control function. The control device has a 32-bit MPU for quick response and high-accuracy.
  • Contributes to energy saving:
    A substantial energy saving is achieved by variable-speed control of a square-law reduced torque load such as a fan or pump.
  • Easy maintenance:
    The inverter is air-cooled, requiring no cooling water.
  • Touch panel:
    Start/stop operation, parameter setting, fault display and data monitoring are performed from the touch panel with simple loader functions.
  • Auto-tuning functions:
    Simple, built-in and facilitating testing and adjustment.
  • Fault diagnoses:
    Easily performable.
  • Input transformer:
    A dry-type input transformer is adopted.
