AC current transducers and AC/DC current transducers

AC current transducers and AC/DC current transducers

AC current transducers measure sinusoidal and non-sinusoidal alternating currents. We offer adjustable measuring transducers with flexible power supply or variants with hinged Rogowski sensor for easy installation. For universal AC/DC current measurement, choose between adjustable current transducers for small currents or compact measuring transducers in graded measuring ranges for measuring high currents.

Current measuring transducers for direct, alternating, and distorted currents

Current measuring transducers for direct, alternating, and distorted currents

MCR AC/DC current measuring transducers measure DC and AC currents of all waveforms, as well as distorted currents, and convert them into an analog standard signal. The portfolio is graded with different measuring ranges for currents up to 600 A.

Your advantages:

  • Also suitable for decentralized use due to the compact dimensions
  • Variable mounting on DIN rail or mounting panel
  • Easy wiring due to plug-in connection terminal blocks
  • For insulated conductors up to 32 mm in diameter
Current measuring transducers for direct and alternating currents

Current measuring transducers for direct and alternating currents

The DIN-rail versions of the MCR AC/DC current measuring transducers measure DC and AC currents of all waveforms and convert them into an analog standard signal. Choose between variably configurable devices for the precise mapping of small measuring ranges up to 55 A.

Your advantages:

  • Quick basic configuration via DIP switches
  • Enhanced configuration and diagnostics options via software
  • Optimized mapping of the measuring range with programmable upper and lower limits

Current measuring transducers for sinusoidal alternating currents

Current measuring transducers for sinusoidal alternating currents

The AC current measuring transducers in the MACX MCR product family also measure sinusoidal AC currents and convert them into an analog standard signal. The products are configurable and provide you with a variable supply concept.

Your advantages:

  • Input and output signal setting via DIP switch
  • Versions for global use with wide range power supply
  • Voltage bridging via the DIN rail connector (24 V)
  • Operating state diagnostics by means of an LED on the front
  • Protection against interference with 3-way electrical isolation
Current relays

Current relays

The current relay converts sinusoidal 50 Hz/60 Hz AC currents into binary switching signals. Current detection takes place inductively via the conductor led through the module. The switching thresholds are set roughly via internal DIP switches, with fine adjustment performed using a potentiometer on the front. A high-quality changeover contact relay with a gold layer is located on the output side. It can be operated in both open and closed circuit current behavior.

Your advantages:

  • Adjustable switching hysteresis
  • Relay changeover contact output
  • 3-way isolation
  • Adjustable open and closed circuit current behavior
  • The switching point is freely selectable within the measuring range of 0 to 16 A AC
