Bridge rectifiers and half-wave rectifiers

Rectification

Bridge rectifiers and half-wave rectifiers are used to connect DC loads to AC power supplies, e.g. electromagnetic brakes and clutches (ROBA-stop®, ROBA®-quick, ROBATIC®), as well as solenoids, electrovalves, contactors, switch-on safe DC motors, etc.

Brake rectifiers
Rectification

  • Matched to drive components
  • Different input voltages possible
  • EMC-compliant installation possible
  • Can be used on the AC or DC side

Bridge rectifiers and half-wave rectifiers are used to connect DC loads to AC power supplies, e.g. electromagnetic brakes and clutches (ROBA-stop®, ROBA®-quick, ROBATIC®), as well as solenoids, solenoid valves, contactors, switch-on-safe DC motors, etc.

This is what AmP brake rectifiers do; other rectifiers from mayr®:

  • matched to the function of brakes & drive components
  • available for input voltages of 230V, 400V, 500V or 600V
  • EMC-compatible installation possible
  • Can be installed on the AC or DC side

Brake rectifiers available as bridge rectifiers or half-wave rectifiers

Their mode of operation has rectifiers from mayr® power transmission have in common with all commercially available half-wave and bridge rectifiers: The clutch and brake rectifiers convert alternating current into direct current in order to Electromagnetic clutches and brakes to be supplied. Which brake rectifier is used depends on the application of the respective brake. The same applies to the use of rectifiers for clutch operation:

  • Half-wave rectifier: The rectifier uses a diode to generate a pulsating DC voltage. This electronic component is used when only a low auxiliary voltage is required.
    Half-wave rectifiers are available for input voltages of 230V, 400V, 500V and 600V, while the peak reverse voltage is 1600V or 2000V.
  • Bridge rectifier:Unlike the half-wave rectifier, the bridge rectifier produces an approximately equal output voltage. The component uses four diodes for the two-way rectification.
    Bridge rectifiers are available for the input voltage of 230V. The peak reverse voltage of the brake rectifier or clutch rectifier is 1600V.

Safe brake rectifiers & clutch rectifiers according to recognised guidelines

All electronic components from mayr® power transmission as well as the products from the safety clutches, safety brakes and shaft couplings business units meet the highest safety guidelines, compliance with which is ensured by tests and certifications.

For the clutch and brake rectifiers from mayr®, the declaration of conformity is available, which follows the EU directives for low voltage 2014/35/EU and electromagnetic compatibility 2014/30/EU. In the operating instructions, installers will also find information on AC-side and DC-side installation as well as on the safety regulations according to VDE 0580. Integration into an EMC-compliant overall system is also possible.
