HAIS100-P is Current Transducer. A current transducer, also known as a current sensor or current transformer, is an electrical device used to measure or monitor the electric current flowing through a conductor or a circuit. It works by transforming the primary current passing through it into a secondary current or voltage that is proportional to the primary current but at a reduced magnitude.

For the electronic measurement of currents: DC, AC, pulsed…, with galvanic separation between the primary circuit and the secondary circuit.
