DC current sensor 100A DC Current probe 1W-UNI, shunt 0-100 A, bidirectional, up to 60 V, 1-Wire UNI - HW group 600678

In 48 V systems and UPS battery strings, the DC current tells you whether an overload is building or the battery is discharging. The 100A DC Current probe 1W-UNI measures up to 100 A in both directions with 2 % accuracy and reports via the 1-Wire UNI bus to Poseidon2 or Ares.

Benefits

• Direction aware: charging reads positive, discharging negative.
• Wide range: 0-100 A DC with 0.1 A resolution.
• Low loss: 0.6 mOhm shunt, 60 mV drop at 100 A.
• Isolated: the 1-Wire UNI bus is electrically isolated from the measured circuit.
• Bus powered: 5 V via RJ11 at 3 mA, no power supply needed.

Applications

• Battery strings of large UPS systems in data centers
• 48 V DC power in telecom equipment
• 12 V or 24 V DC systems, for example in railway technology
• Early warning of overload and current direction changes

Compatibility

• Connects to 1-Wire UNI RJ11 ports on Poseidon2 and Ares
• For currents up to 30 A, choose the 30A DC Current probe 1W-UNI (600677)
