AC/DC contactless TRMS direct and alternate current (± 50 A) transducer, Hall Effect. 4~20mA output

T201DCH50-LP is an isolated, contact-less direct and alternating TRMS current transducer. The device’s function and look are very similar to those of an active standard CT, but with the remarkable feature of measuring the continuous component of the pass-trough current. For its electrical endurance, ease of use and compact dimensions, the T201DCH50-LP fits every kind of current measurement up to 50 Adc or 50Aac.

    Specifications:
  • Direct and alternating current transducer galvanically insulated from the measuring circuit.
  • Measurement principle: Hall Effect
  • Possibility to measure the direct and alternating component of TRMS current.
  • No shunt, no wasted power of primary current circuit and no dissipation.
  • Unipolar or bipolar measure.
  • High measurement accuracy: 0.5 %.
  • Suitable for Seneca modules with power supply sensors at 12V and input 4-20 mA.
  • Two DIP-Switches selectable ranges.
  • Damping filter availability to improve stable reading.
  • Suitable for batteries , battery chargers, solar panels, power units and generic dc loads.
  • Compact overall dimensions: 41 x 44 x 26 mm.
