TD350 Series VFD Optional peripheral accessories
-353-
The VFDs of 220V (18.5–55kW), 460V (HD (CT)≥37kW), and 575 (≥22kW) can be connected to
external DC reactor for the improvement of power factors and the avoidance of damage from high
input current to the rectifying components because of the high-capacity transformer. The device can
also cease the damage to the rectifying components which are caused by supply net voltage
transients and harmonic waves of the loads. If the distance between the VFD and motor is longer
than 100m, contact TECHTOP technical support.
