DB2-AC
![]() |
Key features
|
The DB2-AC 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 Digitron 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.
