30A AC Current probe 1W-UNI 2

30A AC Current probe 1W-UNI 2 is a sensor for indirect single-phase measurement of AC current up to 30A without cutting the wire. 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 is suitable for Poseidon and, Ares product family.

  • Current range of the transducer: 0–30A AC
  • Measurement accuracy: 2%
  • Electrical isolation: The 1-Wire UNI bus is electrically isolated from the measured circuit.
  • A/D converter resolution: 16 bits
  • Display resolution: 0.1A
  • Measured voltage: max. 400V
  • Measurement without cutting the measured wire
  • Operating temperature/humidity: 0°C to 40°C (32°F to 104°F), RH < 80%
  • Storage temperature/humidity: -10°C to +50°C (14°F to 122°F), RH < 70%
  • The length of lead wire between the transformer and converter: 1m
Applications and usage: 
  • The current transducer (“CLAMP METER”) clamps around the line (L) or neutral (N) wire carrying the measured current.
  • The wire under measurement must be insulated!
  • The “CLAMP METER” and “Converter” must be connected using a double insulated wire.


To insert the wire for measuring, unlock the clamp-on core and insert one live wire. Then, close the core and engage the lock.


Note:              Inserting two or more wires makes the measurement impossible.
The wire must lead freely through the core. Do not wrap the wire around the core.

Together with a Poseidon unit, the sensor can serve as an early warning system against overloading the electricity supply or its individual lines. 30A Current probe 1W-UNI 2 consists of a clamp-on current transducer (CLAMP METER) and a 1-Wire converter unit.
