3-Channel Networked DC Voltage Level Sensor
The 3-Channel Networked DC Voltage Level Sensor from Fidar Electronics reads DC voltage from 0 to 24 V and records how it sags over time. It runs standalone on its own IP address with a built-in web page.
Measures DC voltage from 0 to 24 V
Three independent input channels in one unit
Under- and over-voltage alarm thresholds
Built for battery and control-supply health
Own IP address and built-in web page
Powered by PoE or a 48 V adapter
DHCP or a static IP address
SNMP monitoring in PRTG and SolarWinds
A DC voltage level sensor reads the actual value from 0 to 24 V, not merely whether voltage is present. On battery systems, 12 V and 24 V control supplies and solar circuits, a slow sag is the first evidence of an ageing battery or an overloaded supply. Batteries rarely fail all at once — for weeks beforehand the on-load voltage creeps down, and a threshold catches it then rather than when service is already lost.
