For energy saving operation of large capacity Pumps or Motors
Excellent in impedance consistency with disk type secondary-winding when connecting to large capacity inverter
Therefore voltage fluctuations can be reduced.
Installed in a direct inverter system for energy saving operation of
industrial pumps or motors
Connection example
Multiplexing example by transformer
Property
Excellent in impedance consistency
Fit for large capacity and high voltage applications.
Excellent
in short circuit mechanical strength
Low noise and compact
About 25%~30% down-sized with cooling fun system compared to self-cooled
transformer of the same capacity
Control windings for cooling fan operation is built in
