T201DCH 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 T201DCH fits every kind of current measurement up to 50 Adc or 50 Aac.
