Innovative combination of shunt and tank level module.
SC503 is a high precision combo shunt for PICO battery monitor with:

  • 2x voltage
  • 2x temperature
  • 1x JST socet (temperature sensor)
  • 1x current sensor up to 500A for up to 75V systems

It can be used for monitoring current draw of heavy consumers (inverters, bow and stern thrusters, anchor winches) and current generators (shore power chargers and solar panels). Additionally, it allows monitoring tanks for fuel, fresh and grey water.



SC503 is an innovative combination of shunt and tank level module. SC503 active combo 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…

It is equipped with one additional battery voltage input (2 in total). The integrated tank level has 2 resistance type inputs for monitoring tank level or temperature and an additional JST socket for temperature sensor with an JST connector. Additionally, the SC503 module 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.

SC503’s innovative protected architecture allows wiring in either negative (up to 72V) or positive (up to 24V) side.
