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 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 modules). It also enables the monitoring of tanks for fuel, fresh water and grey water.

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

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

The integrated tank level has 2 resistance inputs for monitoring the tank level or temperature and an additional JST socket for the temperature sensor with JST connection. In addition, the SC303 module can also be used to monitor the power consumption of large consumers such as inverters, bow and stern thrusters and anchor winches and power generated by generators such as shore power chargers, solar modules, hydro and wind power generators.

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).
