Simarine SPDU52

Simarine SPDU-52 – Intelligent power distribution for caravan and marine systems

The Simarine SPDU-52 is a versatile power distribution unit designed for demanding caravan and boat installations. It serves as a central connection element for measurement modules, shunts, and sensors controlled via a Simarine VIA panel. With its high precision and robust construction, the SPDU-52 ensures reliable power distribution in your mobile power system.

Versatile connection options

• 3 SICOM interfaces: Two bidirectional ports for power supply and data transmission and a dedicated connection for the caravan panel.
• Integrated battery support: Support for main and starter batteries – with an output voltage of 8-22 VDC.

Precise energy monitoring

• 4 current measurement channels: solar, charger, main and starter battery – with ±2% accuracy.
• Voltage measurement: 0–35 VDC with ±0.5% accuracy.
• Resistance measurement: 0–65 kOhm with ±3% accuracy – ideal for tank sensors.

Modular system for maximum scalability

Expand your system with up to:

• 6 batteries
• 24 shunts
• 10 temperature sensors
• 14 tank level sensors
• 2 tilt sensors

Robust for mobile use

With a temperature range of -10 °C to +70 °C, the SPDU-52 is suitable for extreme conditions in caravan and boat installations.

Important: A Simarine VIA panel is required for control and visualization – this is available separately.

The SPDU-52 is the ideal solution for anyone looking for a reliable, modular, and scalable power distribution system in mobile applications – precise, compact, and dependable.
