ZigBee module for alternate current measurements
ZED-3IAC-M

Key features

3 inputs 5A/380V compatible with most popular commercial current transformers (not included)
Simple and quick installation, without services
breakdown
Alarm thresholds
Sampling and transmission rates are confi gurable
Battery powered
Internal antenna

The ZED-3IAC-M is a battery supplied ZigBee device which can perform alternate current measurements on 3 channels and send these values at regular intervals to a Gateway of the 4-noks products family.
This device may be confi gured to manage alarm thresholds when exceeding maximum or minimum levels of measures. It is also possible to adjust the sampling and data transmission rate to improve battery duration.
