Description
±800 V DIN RAIL-MOUNTABLE VOLTAGE SENSORS
GENERAL DESCRIPTION
The ModuLink ±800 V isolated voltage sensors are easyto-use devices, tailored for power electronics applications.
When employed with imperix’s BoomBox control platform, the sensors provide plug&play connectivity and can be directly powered by the control platform.
The devices produce a balanced full-differential output signal, proportional to the sensed voltage.
For best EMC performance, the output signal is typically meant to be carried by a shielded twisted pair embedded in RJ45-type cables.
Modulink sensors can be easily clipped on 35mm DIN rails and are compatible with up to 6 mm2 wires.
They guarantee the galvanic isolation of the sensing circuit up to 1 kVRMS
