ACS880-604 Brake choppers and brake units
Description
Brake choppers and brake units are used for resistor braking. They handle the energy generated by decelerating motors for example in emergency stops. Whenever the voltage in the drive’s common DC bus exceeds a certain limit, a braking chopper connects the bus to a braking resistor. HighlightsACS880-604 Brake choppers and brake units
