brake units & brake resistors: dynamic braking for variable frequency drives & servo drives

braking units (brake choppers) are electrical switch. They limit the DC bus voltage by switching the braking energy to braking resistors where the braking energy is converted to heat.

braking units (brake choppers) are automatically activated when the actual DC bus voltage exceeds a specified level depending on the nominal voltage of…
