Leading Technology

• Multi-pulse input rectication

reduces input current harmonic

distortion, meeting IEEE 519-1992

• Advanced drive concept provides

multilevel output voltages and

enhanced motor operation

• Advanced control functions

enhance adaptability against

instable grid

Protection Features

• Over current

• Over load

• Transformer over temperature

• MVD over temperature

• Under voltage / over voltage

• Motor overload (external)

• Blower fault

• High voltage cabinet door open

• Cabinet air pressure abnormal

• Output short circuit

• Input / output phase loss

• Communication fault

• Output fault to ground

Enhanced Process & Quality

Control

• Built-in proportional integral

differential (PID) controller

enhances control of process

variables such as ow and pressure

• Ride through and ying start

features ensure a more continuous

process in spite of input voltage

dips

• Friendly user interface provide

easy-to-use system integration

Control & Monitoring Features

• Frequency reference (Hz)

• Actual frequency (Hz)

• Input / output power / current /

voltage

• Cumulative operating hours

• Drive status

• Status of system bypass switches

and MCB

• Analog inputs / outputs monitoring

• Fault / Alert messages

• Fault diagnosis function

• Ride-through and ying start

functions

Lower Cost of Ownership

• System efciency is more than

98.5% (without phase-shifted

transformer)

• Optimized pump and fan operation

ensure signicant energy savings

and short return on investment

• Integrated transformer enables

a three-cable-in-three-cable-

out installation concept using

considerably less engineering effort

• Reduced mechanical stresses

eliminate hammer effect in pipelines

and vent ducts, and lowers

maintenance cost

• Multilevel voltages and motor soft

start minimize stresses
