HWg 100A DC Current probe 1W-UNI

100A DC Current probe 1W-UNI is a set of shunt and converter that can measure DC current up to 100A. The shunt is connected directly (interrupting the wire) into the measured circuit. The DC current is measured in both directions (distinguished by the sign).

The 1W-UNI output can be connected to Poseidon2 or Ares devices. Together with one of these units, the current probe can serve as an early warning of overload or current direction change (charge/discharge).

The probe is suitable for input power monitoring in 12V / 24V or - 48V DC powered systems, providing battery charging or energy consumption monitoring in telco applications.

Applications and Usage

In combination with a Poseidon2 or Ares unit, this probe can be used for overload or change of DC current direction monitoring. Examples are

• in high-capacity UPS's,
• in telecommunications devices,
• in railway applications.

Package contents includes

• 1x measuring shunt
• 1x 1-Wire UNI converter
• 1x printed manual

Configuration Diagram

• The shunt is connected directly to the 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 "-").
• The shunt is connected to the converter by 1 m long two line wire. The length of the wire cannot be changed.
• The shunt resistor and the converter are adjusted to each other for highest accuracy and they cannot be swapped.
