SC303 Digital Shunt

RRP £106.72


SC303 is an innovative combination of shunt and tank level module.

SC303 active combo shunt precisely monitors battery voltage on 12V, 24V, 48V, 60V and 72V systems, battery temperature and continuous currents up to 300A (400A peak). It’s suitable for maximal power of 3600W at 12V or 7200W at 24V. 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 SC303 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.

SC303’s innovative protected architecture allows wiring in either negative (up to 72V) or positive (up to 24V) side.
