Bridge/half-wave rectifier (optional)

BEG-561-
The bridge/half-wave rectifiers are used to supply electromagnetic DC spring-applied brakes which are ap-
proved for the use with such rectifiers. Other use is only permitted with the approval of INTORQ.
Once a set over-excitation time has elapsed, the bridge/half-wave rectifiers switch over from bridge rectifi-
cation to half-wave rectification. Depending on the design of the load, an improvement of the switching be-
haviour or a reduction in performance is possible.
