Engineering performance

Built for dynamic current measurement

High Accuracy

Reference-level accuracy down to < ±0.2% at nominal current on selected ratings.

Fast Response

Response time below 1 µs on the validated OPCO references.

Wide Bandwidth

DC measurement with bandwidth up to 200 kHz depending on current rating.

Galvanic Isolation

6 kV RMS dielectric withstand between primary and secondary circuits on the validated references.

Power Electronics Ready

Designed for current feedback in converter and control architectures.

Standards & Compliance

Reference-level compliance made visible

Standards and compliance depend on the selected OPCO reference. Only validated requirements are presented at family level; detailed conformity information remains available by reference.
