Innovative combination of shunt and tank level module. SC303 is an active combo shunt for PICO battery monitor with 2x voltages, 2x tank level or temperature, 1x socket for temperature sensor with JST connector and 1x current sensor up to 300A 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.
