PMB, PME, PMG

Direct current is required to operate the PRECIMA spring-applied brakes.
If required, we therefore supply suitable rectifiers according to your requirements.

DIRECT CURRENT CAN BE PROVIDED BY:

• Direct supply (battery, DC mains, etc.)

• Half-wave or bridge rectifier

• Fast excitation rectifier

OUR TYPES AND DESIGNATIONS:

• 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.
