FRS, FL – Coreless integral sensors with open control loop
Our brand new FRS and FL product families are designed for the electronic measurement of direct, alternating and pulsed current with galvanic isolation between the primary and secondary circuits.

The FRS current sensors enable the measurement of currents up to 9000 A, while the FL sensors can reach up to 42 kA.
Both product families are available with either a current output (4-20 mA) or an instantaneous voltage output (0-5 V).
