HWG-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.
