Current sense optical fiber link EFL-I

Description

EMCgear Current sense analog fiber link EFL-I is a range of products primarily designed for use in EMC test labs or anywhere monitoring current, digitizing, and transferring these signals between two places takes place.

Link is available in 6 current ranges (both unipolar and bipolar) to cover most of the requirements that your device under test may have.

High-speed communication link between EFL-I devices with real-time CRC protection ensures absolute signal integrity.

Rugged aluminum enclosure and embedded filters offer both perfect EMI behavior and high immunity performance for harsh EMC environments.
