The TMU variable frequency drive is available for power supply of 208, 230, 460 or 575v through the use of
an autotransformer. In addition, a line reactor is used to protect the TMU VFD against voltage spikes. Both
the autotransformer and the line reactor are mounted to the trolley idler side plate under a cover. For a power
supply of 400v/50Hz, a transformer is not required. The VFD controls are totally enclosed, and the enclosure
is mounted to the motor.
