Wireless DC Voltage Detector

The Wireless DC Voltage Detector from Fidar Electronics reports whether a DC circuit up to 60 V is energised and raises the alarm the moment it is not. It links over a LoRa radio with no cabling at all.

  • Detects DC voltage presence up to 60 V
  • Immediate supply-loss alert with a timestamp
  • Covers 12, 24 and 48 V industrial supplies
  • LoRa radio link up to 1 km line of sight
  • AES-128 encrypted payloads
  • Pairs with the FWL1600-01 LoRa card
  • No cabling; pairing takes seconds
  • Low-battery warning per node

A DC voltage detector reports whether a DC circuit up to 60 V is energised. On −48 V telecom sites, 24 V control panels and battery systems a supply loss is usually silent: nobody notices until a service drops, and by then nobody knows when it went. This detector raises the alarm at the moment it happens and records exactly when.
