Product Description
FSDrive-MV1S Series Inverter
The FSDrive-MV1S series Inverter is a new series PWM type medium voltage inverter unit. This unit offers
the following three features:
• Enables a clean power supply minus excessive harmonics.
This Inverter unit causes little voltage distortion and uses little current.
• Achieves high efficiency and high power factor.
Inverter efficiency: approx. 97%, power factor: 0.95 or more (at rated rotation and 100% load)
• Achieves output voltage and current of approximate sinusoidal wave.
Since the Inverter unit has little surge voltage that affects motor, existing motors or cables can be used
without modification.
Torque ripple is minirized.
Configuration
Fig. 1.3 shows typical configurations of FSDrive-MV1S series Inverters.
As shown in Fig. 1.3, the FSDrive-MV1S series Inverter is composed of three panels:
• Transformer Panel
• Power Cell Panel
• Control Panel (Some models have one panel commonly used as Control and Transformer Panel because of
their capacities.)
Transformer Panel
The Transformer Panel houses a dry-type transformer, 3 kV/630 V or 6 kV/630 V with multi-windings. The
secondary winding of the multiple transformer is composed of three steps (9 windings) for 3 kV class or 6
steps (18 windings) for 6 kV class, each of which is connected to a 3-phase input of the Power Cell.
Several cooling fans are mounted on the Transformer Panel, in which pressurized ventilation fans are stored.
Cooled air brought through the filters on the Transformer Panel and Power Cell Panel front faces passes the
transformer section and Power Cell fin section, flows into the air duct in the panel rear, and is exhausted
through the fan section panel after cooling the main circuit components.
