AC digital units

Rapid replacement if needed

The single power units BUM 60, 61, 62, 63, 64 consist of the grid-side feed-in converter and the motor-side inverter. The BUS 60, 61, 62, 63, 64 power modules only contain the inverter on the motor side. The power is supplied via the DC link connections.

BUC 624 and BUC 625 power feed/feedback units are line-side power converters for feeding the DC link of the BUS 62x power modules.

BUG 622 and BUG 623 basic power feed units are line-side power converters for feeding the DC link of BUS 62x power modules.

By using the capacitor unit BUK 622 it may be possible to replace a ballast unit which normally converts the regenerated energy into heat. Furthermore, it is used wherever the DC link voltage must be maintained in the event of a short-term power failure.

BUB 622 is a ballast unit specially designed for operation with BUM 62, 63, 64 inverters.
