Simarine SC303 Digital Shunt 300 A

Active shunt resistor SC303

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

• 2 voltage sensors
• 2 tank level or temperature sensors
• 1x JST Socet (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 large consumers (inverters, bow and stern thrusters, anchor winches) and power generators (shore power chargers and solar panels). It also enables monitoring of fuel, fresh water, and grey water tanks.

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

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

The integrated tank level indicator features two resistance inputs for monitoring the tank 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 large consumers such as inverters, bow and stern thrusters, anchor winches, and the power generated by generators such as shore power chargers, solar panels, hydroelectric generators, and wind turbines.

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