DC current sensor 30A DC Current probe 1W-UNI, shunt 0-30 A, bidirectional, up to 60 V, 1-Wire UNI - HW group 600677

Smaller DC loads and battery circuits need a shunt that still resolves low currents cleanly. The 30A DC Current probe 1W-UNI measures up to 30 A in both directions with 2 % accuracy and 0.1 A resolution, reporting via 1-Wire UNI to Poseidon2 or Ares.

Benefits

• Direction aware: charging reads positive, discharging negative.
• Sized for smaller loads: 0-30 A DC with 0.1 A resolution.
• Matched shunt: 2 mOhm, 60 mV drop at 30 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

• 48 V DC supply of individual racks and network equipment
• Battery circuits of smaller UPS systems
• 12 V and 24 V DC systems in telecom and 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 100 A, choose the 100A DC Current probe 1W-UNI (600678)
