30A Current probe 1W-UNI:
0–30A sensor for indirect AC current measurements
30A Current probe 1W-UNI is a 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.
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 consists of a
clamp-on current transducer (CLAMP METER) and a 1-Wire
converter unit.
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.

Basic features:
Current range of the transducer: 0–30A
Measurement accuracy: 2%
Electrical isolation: The 1-Wire UNI bus is electrically isolated from the measured circuit.
A/D converter resolution: 10 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%
Connecting the converter
The current transducer is connected to the 1-Wire UNI converter with a two-wire, double insulated
cable. Pay attention to the cable polarity.
The polarity is indicated on both the probe and the converter.
The NC terminal at the converter is not connected.
