Simarine SC503 500A Active Digital Combo Shunt

Advanced Dual Battery and Tank Monitoring for PICO Systems

The Simarine SC503 is a highly versatile active digital combo shunt engineered to elevate your PICO battery monitoring system. Designed for robust 12V, 24V, and 48V power networks (compatible up to 75V), this advanced module combines high-precision current measurement with comprehensive voltage, resistance, and temperature monitoring. By consolidating multiple sensor inputs into a single compact unit, the SC503 reduces wiring complexity and simplifies system integration for marine vessels, camper trailers, and off-grid setups.

Measure Heavy Current Draw with Confidence

Monitoring high-capacity electrical circuits requires reliable and accurate hardware. Featuring a continuous current rating of 500A and capable of handling peak currents up to 1000A for short durations, this dual battery shunt is perfectly suited for demanding applications. It effortlessly tracks the power draw of heavy consumers such as high-output inverters, bow and stern thrusters, or anchor winches. Alternatively, it can monitor high-yield current generators like large solar arrays and shore power chargers. The robust M10 bolt terminals ensure a secure, low-resistance connection, minimising the risk of voltage drops or heat buildup during intensive use.

All-in-One Sensor Integration

Beyond standard current tracking, the SC503 functions as a multi-purpose sensor hub. It features two dedicated voltage inputs and two resistance inputs, allowing users to monitor a secondary battery bank alongside fuel, fresh water, or grey water tank levels. Additionally, the unit provides temperature monitoring capabilities through a dedicated JST connector socket for an NTC 10k temperature sensor. This holistic approach to system tracking gives you complete oversight of your critical utilities from a single interface, eliminating the need to install separate, standalone tank or temperature modules.

Seamless Network Expansion

Integration into your existing monitoring network is straightforward. The shunt is equipped with dual RJ9 SiCOM ports, enabling seamless data communication and simple daisy-chaining with other Simarine modules or directly to your PICO display. The included green 6-pin terminal block makes wiring your voltage and resistance inputs quick and secure. With a highly accurate 0.01A resolution and a fast 100ms sampling rate, the SC503 ensures your digital display updates with real-time, precise system data.
