3-Channel Networked AC Voltage Detector
The 3-Channel Networked AC Voltage Detector from Fidar Electronics reports whether an AC line up to 220 V is live and timestamps every loss and restore. It runs standalone on its own IP address with a built-in web page.
Detects AC voltage presence up to 220 V
Three independent input channels in one unit
Immediate power-failure alert with a timestamp
A definite two-state answer, no value to interpret
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
An AC voltage detector reports whether a line is live. Unlike a level sensor that returns a number, it gives a definite two-state answer, which is exactly what the job needs: mains-failure alerts, proving a transfer to generator or UPS, and confirming that critical circuits are energised. Every transition is timestamped, so the outage duration stays in the record instead of relying on someone's memory.
