The bridge-half-wave rectifiers are used to supply electromagnetic DC spring-applied brakes which are ap-
proved for use with such rectifiers. Other use is only permitted with the approval of INTORQ.
Once a set over-excitation period has elapsed, the bridge-half-wave rectifiers switch over from bridge recti-
fication to half-wave rectification.
Terminals 3 and 4 are located in the brake’s DC circuit. When used in passenger elevators, these contacts
must not be used to switch off the brake. Be sure to provide a protective circuit according to the "Switching
suggestions" figures in the chapter Electrical connection, Page 38.
6.3.2
Bridge rectifier for brakes without holding voltage reduction
BEG-142-270
The four-pole bridge rectifiers are used to supply electromagnetic DC spring-applied brakes which are ap-
proved for use with such rectifiers. Other use is only permitted with the approval of INTORQ.
