 Elimination of isolation transformer results in lower
losses and saved space
 An integrated system solution for fewer connections
and reduced installation costs
 New or existing motors
 Small system footprint
 3 cables in/3 cables out on entire system for easy
installation
 Low line harmonics and high power factor (typical
current THD < 5%, PF > 0.98)
 Fan control power and control circuit power
supplied internally
 Input starter optional
 Optimum installation flexibility with connection to
indoor or outdoor isolation transformers
 Compact packaging for smallest footprint
requirements
 New or existing motors
 3 cables in/3 cables out for easy installation
