Nereide 2

A complete digital switching solution for yachts

nereide 2 control panel

Classy design

An elegant combination of tactile buttons and a digital display. The aluminum casing and optically bonded display give the control panel a high-end look that complement the interior of your boat or yacht.

The slightly raised and rounded buttons provide a comfortable feel when touched. 

The front can be flush with the surface or only 5 mm above it. 

Also the 12V distribution unit is one of a kind

  • It’s sleek, compact and has a low profile.
  • It features an ultra durable circuit board with protective coating.
  • Sleek aluminum casing protects the circuit board and provides efficient passive cooling.
  • For easy access and extra protection for relays and fuses, we added removable covers that require no tools to open.

Partnership with HanseYachts AG

We are honored that our Nereide 2 complements the yacht’s interior of one of the world’s largest manufacturers of sailing yachts, HanseYachts AG.

This leading German yacht company owns 6 innovative brands, you can find the Nereide 2 at Hanse, Dehler and Fjord. 

Ultra low power consumption

The distribution unit uses only 10 mA, while the panel consumes 30 mA when switched off with the logger active.

Nereide 2 can be placed between the main battery and the main switch. The beauty of this is that it won’t drain your battery if you don’t sail for a while. Even in this low power mode, the system offers comprehensive remote monitoring and management functions.

NMEA 2000 compatible

Switch your appliances directly from the plotter. Nereide 2 digital switching system is compatible with the NMEA protocol to ease the control of your yacht. 

PICO battery monitoring system built-in

The Nereide 2 offers everything the Pico monitoring system delivers: Battery, tank and temperature monitoring as well as air pressure measurement.

DC unit with 31 manually over-rideable output channels

Let’s take a closer look at the DC power distribution unit. It features 30 outputs with a current rating of up to 10 amps and 1 output with a current rating of up to 30 amps. All-together, the unit is rated for a maximum current of 200 amps. To protect your consumers standard automotive mini-fuses are used and are easily replacepable.

Any kind of error, for example blown fuse, stuck relay or lack of supply voltage will be indicated on the corresponding button on the control panel.

AC distribution unit with motorized or standard minuature circuit breakers (MCB) and RCBO switch

Distribute AC power safely with one of the two power distribution units. The only difference between them is whether a circuit breakers can be disconnected and reconnected electrically (SAC23R-RCBO) or manually (SAC23M-RCBO).

Each unit has 2 selectable inputs for power sources (shore, inverter, or generator) and 3 output channels with overcurrent protection by miniature circuit breakers (MCBs).

But not only that, the units also have an integrated RCBO (residual current circuit breaker with overcurrent protection) that provides protection in the event of a short circuit or overload. It also protects the vessel’s occupants from electric shock.

SAC23R-RCBO has motorized RCBO and MCBs, which enables remote switching of circuit breakers, even if the circuit breaker trips.

Both inputs are rated for 32 A current, and the output current is limited to 20 A per channel. Each channel is monitored and is capable of detecting a circuit breaker trip or voltage deficiency. The error is signaled to the control panel and is indicated by changing the corresponding button’s background color (from blue to red).

For measuring current consumption, there is also an integrated shunt resistor. The units also measure input voltage.

They have an output for daisy-chaining additional AC distribution units.

Wiring and installation
made easy

For you to install the unit quickly and easily we chose wiring via standard WAGO® connectors. DC unit and the control panel are connected over a single SiCAN cable. The Nereide 2 control panel is separate from the power unit. This makes it even easier to install. 

With care for
the Earth in mind

Aluminium & Glass. 

That’s all you’ll see when looking at the control panel.
