Simarine Nereide 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 an elegant design with robust technology and offers a high degree of functionality, safety, and user-friendliness – both in operation and installation.

High-quality workmanship and intuitive operation

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

Compact DC power distribution with 31 outputs

The distribution unit is flat, with a robust circuit board and efficient passive cooling thanks to the 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 mini fuses ensure safety. Fault conditions such as tripped fuses or defective relays are immediately visible via a red LED ring indicator on the affected button.

Powerful features at a glance:

• Buttons configurable as manual or momentary switches
• Fault indication by color change of the button
• 8 tank and 7 voltage inputs
• Compatibility with all SiCom modules
• Automatic backlighting
• Display for navigation lights

AC modules for safe 230 V power distribution

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

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

Low self-consumption & clever energy monitoring

With only 10 mA current consumption (distributor) and 30 mA in sleep mode (panel), the Nereide 2 is particularly energy-saving. Even during long periods of non-use, your onboard battery is spared. Via the integrated Pico monitoring system, you always have access to battery status, tank levels, temperature, and air pressure.

Flexible, networked, future-proof

The Nereide 2 is NMEA 2000 compatible and can be seamlessly integrated into existing onboard networks – for control directly via the plotter. Thanks to its modular design, SiCAN communication, and WAGO® connectors, installation is quick and straightforward.

Developed in collaboration 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.
