Description
The Flux Gate AC/DC Current Sensor is a high accuracy DIN rail mounted sensor designed for reliable measurement of both AC and DC currents in low voltage electrical systems. Using closed loop flux gate technology, the sensor provides stable and linear current measurement with low hysteresis, low temperature drift, and excellent long term accuracy for demanding monitoring applications.
Suitable for power quality monitoring, EV charging, battery systems, solar applications, industrial automation, railway signalling, and UPS systems, the sensor delivers a proportional mV output compatible with power quality analysers, PLCs, SCADA systems, and other instruments with mV inputs. It is optimised for use with the Miro PQ45 and Miro PCM platforms.
