Active shunt for PICO battery monitor with:

  • 1x voltage
  • 1x temperature
  • 1x current sensor up to 500A for up to 75V systems

It can also be used for monitoring current draw of heavy consumers (inverters, bow and stern thrusters, anchor winches) and current generators like shore power chargers and solar panels.



SC501 active shunt precisely monitors battery voltage on 12V, 24V, 48V, 60V and 72V systems, battery temperature and continuous currents up to 500A (600A peak). It’s suitable for maximal power of 7200W at 12V, 14400W at 24V or 28800 at 48V…

Additionally, it can also be used for monitoring current draw of heavy consumers like inverters, bow and stern thrusters and anchor winches and current generated on generators like shore power chargers, solar panels, hydro- and wind generators.

SC501’s innovative protected architecture allows wiring in either negative (low) or positive (high) side. Up to 12 modules can be connected simultaneously for battery (6) and current (6) measurements (only on PICO Battery Monitor).
