HTFLEX3003 is an innovative three-phase current transducer that combines easy use with measurement accuracy thanks to Rogowski method. Flexible clamp kit HTFLEX3003 is a 3 flexible clamps for measuring AC current based on the principle of Rogowski up to 3000A. Scales: 300 / 3000A

HTFLEX3003 transducer is similar in purpose to a CT or current transformer used to measure three phase currents. Figure 1 shows the three phase current probe. The outputs are max 1V~ analogue voltages proportional to the AC currents in the conductors. The output signals are isolated form the hazardous conductor potentials and are exact replicas of the current waveforms in the conductors. The output signals are available via a 3 pin connector (see Figure 2 below for output signal pin assignment).

HTFLEX3003 transducer requires two 1.5V type AA MN1500 LR6 alkaline batteries for operation. The battery compartment is accessed from the rear of the electronics enclosure. HTFLEX3003 transducer and interconnection cables use double insulation to protect the operator from possible hazardous potentials of the bus. Make sure the electronics package is well away from the bus. Each current probe is rated for Installation CAT III, Pollution Degree 2. The maximum voltage to earth rating for the transducer and cable is 1000V~. The maximum voltage to earth rating for the electronics enclosure is 30V~.
