Simarine SC303 Digital Shunt 300 A

Active shunt resistor SC303

SC303 is an active combined shunt resistor for the PICO and PICO one battery monitors with:

• 2 voltage sensors
• 2 fuel level or temperature sensors
• 1x JST socket (temperature sensor)
• 1 current sensor for up to 300 A for systems with up to 75 V

It can be used to monitor the power consumption of major consumers (inverters, bow and stern thrusters, anchor windlasses) and power generators (shore power chargers and solar panels). It also enables the monitoring of fuel, fresh water, and grey water tanks.

SC303 is an innovative combination of a shunt resistor and a fuel level module.

The active combined shunt resistor SC303 ensures precise monitoring of the battery voltage in systems with 12 V, 24 V, 48 V, 60 V, and 72 V, the battery temperature, and continuous currents of up to 300 A (peak 400 A). It is suitable for a maximum power of 3600 W at 12 V or 7200 W at 24 V. It has an additional battery voltage input (2 in total).

The integrated fuel level module has 2 resistance inputs for monitoring the fuel level or temperature and an additional JST socket for the temperature sensor with a JST connector. In addition, the SC303 module can also be used to monitor the power consumption of major consumers such as inverters, bow and stern thrusters, as well as anchor windlasses, and power generated by generators such as shore power chargers, solar panels, water and wind power generators.

The innovative protected architecture of the SC303 allows connection either on the negative side (up to 72 V) or the positive side (up to 24 V).
