PMB – bridge rectifier
PMBAF – bridge rectifier with overvoltage protection and cage clamp:
The bridge rectifier generates an optimal DC voltage and is available for AC or DC switching.
PME – half-wave rectifier
PMEA – half-wave rectifier with overvoltage protection
PMEAF – half-wave rectifier with overvoltage protection and cage clamp:
The half-wave rectifier halves the required coil voltage, is inexpensive and can be supplied for AC or DC switching.
PMG – fast excitation rectifier:
The fast excitation rectifier is recommended where short ventilation times and low power losses are required.
It combines the advantages of half-wave and bridge rectifiers.
PMGU – fast excitation rectifier with quick shutdown:
The fast excitation rectifier expands the range of functions of the
Standard PMG rectifier for fast shutdown and the Setting the overexcitation time (variant dependent).
PMRU – quick shutdown device:
The rapid shutdown device is used in addition to a rectifier to achieve faster brake application.
PMS – current detection relay:
The current detection relay is used to switch the spring-applied brake on the DC side if there is no neutral conductor to the motor.
