30A Current probe 1W-UNI:
0–30A sensor for indirect AC current measurements

30A Current probe 1W-UNI is a 1-Wire sensor for indirect (without cutting the wire), single-phase measurement of AC current up to 30A. The split-core current transducer can be opened in order to insert a line wire. The sensor is suitable for monitoring power consumption of racks, BTS's or server rooms.

Sensor for measuring current in 230V and 110V installations using a clamp-on probe. Connects to a Poseidion unit with support for 1-Wire UNI (Poseidon 4001, 4002, 2250) or a SiteMon unit. Enables you to create an early warning system against overloading the electricity supply or individual lines.

30A Current probe 1W-UNI consists of a split-core current transducer (CLAMP METER) and a 1-Wire UNI converter unit. The sensor connects to a Poseidon or Sitemon unit using a RJ11 cable (included).

The sensor communicates over the 1-Wire UNI bus (RJ11). Together with Poseidon 4001, 4002, 2250, or SiteMon units, the sensor can be monitored using SNMP, Modbus/TCP, or e-mail (an e-mail is sent if a value exceeds or drops below the specified limit).
