Why excess temperature protection is important for VFD pump inverter?

Excess temperature protection is important for VFD / VSD Constant Pressure Booster Pump Inverter is because it can protect the parts like impeller, mechanical seal, bearing, motor, and the driver itself from damaging by too high temperature.

There are various types of excess temperature protection for VFD / VSD Constant Pressure Booster Pump Inverter. One of them is preventing IGBT from overheat and not to damage the drive. Another is thermal protection which prevents the motor from burning.

As for In-Line water-cooled type VFD / VSD Constant Pressure Booster Pump Inverter, there is another excess temperature protection to make sure the drive does not operate under higher water temperature than the max. setting point in order to protect the dive from damaging.
