Simarine Nereid 2 Control Unit

Simarine Nereide 2 – The digital switch solution for modern yachts

The Simarine Nereide 2 is an advanced, fully digital switch solution specifically designed for use on yachts. It combines elegant design with robust engineering, offering a high level of functionality, safety, and ease of use—both in operation and installation.

High-quality workmanship and intuitive operation

The aluminum housing, optically bonded display, and slightly raised buttons provide a clearly defined pressure point. Depending on the installation variant, the front panel can be flush or protrude by 5 mm—ideal for various on-board design concepts.

Compact DC power distribution with 31 outputs

The distribution unit features a flat design, a robust circuit board, and efficient passive cooling through its aluminum housing. It offers 30 DC outputs up to 10 A and one high-current output up to 30 A – a total of up to 200 A. Standard miniature fuses ensure safety. Fault conditions such as blown fuses or defective relays are immediately indicated by a red LED ring indicator on the affected button.

Powerful features at a glance:

• Buttons that can be configured manually or as push buttons
• Error indication by color change of the button
• 8 tank and 7 voltage inputs
• Compatibility with all SiCom modules
• Automatic backlight
• Navigation light display

AC modules for safe 230 V power distribution

With the optional AC modules SAC15M-RCBO or SAC15R-RCBO, you can control AC power distribution safely and efficiently. Both versions offer:

• Two selectable inputs (e.g. shore connection, generator, inverter)
• Three fused output channels (20 A)
• Integrated RCBO circuit breakers (residual current + overcurrent)
• Remote controllable switches on the SAC15R version
• Display of error conditions directly on the control panel
• Current measurement via integrated shunt

Low self-consumption & clever energy monitoring

With a power consumption of just 10 mA (distribution board) and 30 mA in sleep mode (panel), the Nereide 2 is particularly energy-efficient. Even during extended periods of non-use, your onboard battery is protected. The integrated Pico monitoring system gives you constant access to battery status, fuel levels, temperature, and barometric pressure.

Flexible, networked, future-proof

The Nereide 2 is NMEA 2000 compatible and integrates seamlessly into existing on-board networks for control directly from the plotter. Thanks to its modular design, SiCAN communication, and WAGO® connectors, installation is quick and straightforward.

Developed in cooperation with HanseYachts

The Simarine Nereide 2 is used by renowned shipyards such as Hanse, Dehler and Fjord – a sign of quality and practicality in the premium class.
