Product Information
Product Description
The 1W-UNI DC Current Probe is a precision measurement set consisting of a shunt resistor and converter that can measure DC current up to 20A.. The shunt is inserted in-line with the monitored circuit, interrupting the conductor to enable accurate current sensing.
This probe supports bidirectional current measurement, with polarity indicated by the signal sign. This measurement is useful for distinguishing between charging and discharging currents.
The converter is compatible with Poseidon2 and Ares units (sold separately). These units enable integration with remote monitoring systems for overload detection and current flow direction alert.
Applications and usage:
In combination with Poseidon2 and Ares units (sold separately). this probe can be used for overload or change of DC current direction monitoring
- in large UPS's,
- in telecommunications devices,
- in railways.
Configuration Diagram
- The shunt is connected directly to positive or negative terminal of the monitored circuit. it can be connected any way.
- The positive pin on the converter determines the more positive voltage (power source etc.). The shunt measures positive values from positive to negative. The current flowing in opposite direction is considered as negative (battery charge "+", discharge "-").
- A 1 meter long two line wire connects shunt to the converter. The length of the wire cannot be changed.
- The shunt resistor and the converter are adjusted to each other for highest accuracy. They cannot be swapped.
