AC voltage sensor Sensor 230V AC 1W-UNI, 100-250 V AC, electrically isolated, DIN rail, RJ11 1-Wire UNI - HW group 600602

Voltage dips at a UPS or in a sub-distribution board often go unnoticed until something trips. The Sensor 230V AC 1W-UNI measures mains voltage between 100 and 250 V AC at 1 V resolution and hands a new reading to the monitoring unit roughly every second.

Benefits

• Actual readings, not just on or off: voltage is logged in volts, so fluctuations can be tracked over long periods.
• Safely isolated: the mains side is galvanically isolated from the 1-Wire UNI bus.
• Works on both grids: suitable for 230 V/50 Hz and 110 V/60 Hz.
• Fits the distribution board: DIN rail mounting, 2 modules wide.
• No extra power adapter: powered from the 1-Wire UNI bus at 5 V and 10 mA, with two RJ11 sockets for daisy-chaining.

Applications

• Monitoring the supply at the input or output of a UPS in the server room
• Long-term logging of mains voltage fluctuations in sub-distribution boards
• Detecting power loss at cooling plant and CDU feeds in data centers
• Voltage monitoring at remote sites over GSM with Ares

Compatibility

• Poseidon2, for example Poseidon2 3266 (LAN, SNMP, XML, Modbus/TCP)
• HWg-Ares, for example Ares 12 (GSM)
• Connection to the SensDesk.com portal through the monitoring unit
