Simarine SC503 500 A Combo Shunt for PICO
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Simarine SC503 is a high-current combo shunt for the PICO battery monitoring system. It measures battery current from 0.01 A up to 500 A continuous with ±1% accuracy and 0.01 A resolution, sampling every 100 ms, and handles peaks of 700 A for under 5 minutes and 1000 A for under 1 minute. That makes it the main battery shunt in most PICO installations.
It is more than a shunt. Alongside the current measurement, the SC503 has 2 voltage inputs (0 to 75 V) for starter or auxiliary batteries, resistance inputs R1, R2 and a JST socket (0 to 65 kΩ) for tank senders, and an input for a Simarine NTC 10k temperature sensor. Voltage drop across the shunt is 41.6 mV at 500 A. It can be wired on the negative or the positive side of the battery and connects with M10 bolts.
The module runs from 6 to 35 V DC, draws about 1.2 mA and works from -20 to 70 °C. It measures 125 x 70 x 22 mm and links to the PICO display, or to other Simarine monitoring panels, over the SiCOM data bus. Simarine makes the SC503 in Slovenia and covers it with a 3-year warranty.
