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.
