Bridge/half−wave rectifiers (option)

Bridge/half−wave rectifiers are used for the supply of electromagnetic spring−applied DC
brakes which have been released for operation with such rectifiers. Any other use is only
permitted with the explicit written approval of INTORQ.
After a defined overexcitation time, the bridge/half−wave rectifiers change from bridge
rectification to half−wave rectification. Depending on the dimensioning of the load, the
switching performance can thus be improved or the power can be derated.
