OPCO

200A…2500A


The OPCO is a closed-loop current sensor (also known as a compensated current transducer), designed for the precise measurement of AC and DC currents up to 2500A. This sensor uses Hall Effect technology in a closed-loop configuration, providing high accuracy and excellent linearity in the measurement of both alternating and direct currents.

The OPCO operates with a typical supply voltage of (±15V to ±24V) ±5% and ensures full galvanic isolation between the primary and secondary circuits. This isolation is crucial for protecting sensitive equipment in industrial and high-power environments, where large potential differences can exist between circuits.
