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 specially designed for use on yachts. It combines elegant design with robust technology and offers a high level of functionality, safety, and ease of use – both in operation and installation.

High-quality workmanship and intuitive operation

The aluminum housing, visually bonded display, and slightly raised buttons provide a clearly defined tactile point. Depending on the installation option, the front can finish flush or protrude by 5 mm – ideal for various onboard design concepts.

Compact DC power distribution with 31 outputs

The distribution unit has a low-profile design, with a robust circuit board and efficient passive cooling through the aluminum housing. It offers 30 DC outputs up to 10 A as well as a high-current output up to 30 A – up to 200 A in total. 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 manually or as pushbuttons
• Fault indication via button color change
• 8 tank and 7 voltage inputs
• Compatibility with all SiCom modules
• Automatic backlight
• Display for navigation lights

AC modules for safe 230 V power distribution

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

• Two selectable inputs (e.g. shore power, generator, inverter)
• Three protected output channels (20 A)
• Integrated RCBO protection switches (residual current + overcurrent)
• Remotely controllable switches in the SAC15R version
• Fault condition display directly on the control panel
• Current measurement via integrated shunt

Low power consumption & smart energy monitoring

With only 10 mA power consumption (distribution unit) 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 spared. Via the integrated Pico monitoring system, you have access to battery status, tank levels, temperature, and air pressure at all times.

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 fast 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 practical suitability in the premium class.
