Compact design for space saving
The industry’s smallest-class inverter 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.

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.

-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.

Easy maintenance
-The inverter is air-cooled, requiring no cooling water.
-Start/stop operation, parameter setting, fault display and data monitoring are performed from the touch panel with simple loader functions.
-Simple, built-in auto-tuning functions facilitate testing and adjustment.
-Fault diagnoses are easily performed.
-A dry-type input transformer is adopted.
