The PTA-T-1PH-xxx-LP models are isolated, non-contact TRMS AC/DC or bipolar DC current transducers.
The main specifications of the devices are as follows:
- 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 measurement.
- High measurement accuracy.
- 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.
