Fuji Medium Voltage Inverter FRENIC4600FM５ Features Simple Main Circuit Configuration Low Motor Stress Multi Level PWM Inverter(equivalent to 9 or 17 level inverter) Low surge-voltage to motor, low output current harmonics, and low torque pulsations. Clean Power Input 36-pulse Diode Rectifier Low voltage and current harmonics (no harmonic filters) High power factor : 0.95 or more (no external capacitors) High Efficiency Output transformer-less Efficiency approx.　0.97 (Input transformer and Inverter) Built-in Sequencer Function (option) Communications : Profibus, T-link(Private)

Output voltage waveform Features of Fuji Medium Voltage Inverter Low Motor Stress 6.6kV Inverter Output voltage waveform Fuji Medium Voltage Inverter can operate existing motors without motor de-rating. Low surge-voltage to motor, low output current harmonics, and low torque pulsations.

Input current waveforms High harmonics content Features of Fuji Medium Voltage Inverter Clean power Input Input current waveforms High harmonics content 36-Pulse rectifier Low current harmonics (no harmonic filter). High Power factor, 0.95 or more (no external capacitors).

Features of Fuji Medium Voltage Inverter Stable Control Block diagram of simple sensor-less vector control V/F control system with simple sensor-less vector control provides steady speed control In any load condition. A speed sensor is not required. The controller has 32-bit MPU and DSPs for quick response and high accuracy. Vector control with speed sensor is available(as an option) for equipment having high speed and torque accuracy requirements.

High efficiency, high power factor Features of Fuji Medium Voltage Inverter High efficiency, high power factor Efficiency characteristics (load - efficiency) 60Hz 20Hz Output transformer-less Using Fuji’s unique multi-level PWM control system, the switching loss can be reduced. The reduction of the main circuit parts has also decreased generation of additional loss. The output current waveform is almost sinusoidal, reducing the higher harmonic loss of motors. Using multi-pulse full bridge diode rectifier provides a high-power factor on the power source (approx. 0.95 or more), amd reduces the higher harmonic loss of input transformer primary winding.

Features of Fuji High-voltage Inverter Easy maintenance Operation with LCD display touch panel is available Failure diagnosis is easy The inverter is air-cooled, requiring no cooling water Input transformer is dry-type External cable working is not required of serial panel composition with the inverter panel Front maintenance type Adjustment is easy because of provision of the simple auto- tuning function Enables users to carry out remote monitoring of inverter promptly and easily with their own personal computers
