Highlights

Easy Connection

The switch panels are completely pre-wired. Only the supply line and the
consumers need to be connected at the rear using 6.3 mm spade connectors.
An additional negative lead powers the energy-saving light-emitting diodes
(4 mA at 12 V) and causes them to light up when the circuit is activated. A
"STKZ" labeling sheet with self-adhesive labels is included in the scope of
delivery.

Technology that Endures

For our panels, we deliberately use replaceable, mechanical circuit breakers – for maximum reliability and easy maintenance. Thanks to their well-thought-out design, components can be replaced quickly and easily, minimizing downtime.

The integrated protective function eliminates the need for additional fuses and simultaneously ensures a high level of operational safety. As these are purely mechanical solutions, no additional energy is required for electronics or relays – a clear advantage in terms of efficiency and sustainability.

Smart Position Lamp Monitoring – Safety That Thinks With You

A failure does not go unnoticed: Electronic monitoring immediately detects when a light bulb, LED or even a cable connection fails – in real time and absolutely reliably.

In the event of a fault, you receive a clear, direct indication on the display. The affected position lamp is clearly marked so that you can react immediately without searching.

Built to last

Our aluminum panels stand for uncompromising quality, modern design, and exceptional durability. Crafted from lightweight, high-strength aluminum, they combine stability with elegant lightness – perfect for demanding applications.

The exclusive powder coating, inspired by proven maritime processes, not only reliably protects against external influences but also gives each panel a noble, distinctive surface. In combination with our specially developed color palette, a unique look is created that clearly stands out from the crowd.

For the final refinement, we rely on precise screen printing. The result: razor-sharp, high-contrast representations with high color brilliance and lasting visibility – even with intensive use.

Our FAQ

Here are our customers' most frequently asked questions!

The STV 312/4 SY is a combined circuit distributor with navigation light monitoring and alarm for sailing yachts: 12 circuits with thermal 8A circuit breakers, 4 additional 8A circuit breakers, and a voltmeter with switch and moving coil movement Class 1.5.

The integrated monitoring electronics (POS 6) detect the failure of a light bulb or LED as well as a cable break and indicate this by a flashing LED and an acoustic alarm.

Yes. There are standalone retrofit modules for this: POS-SY for sailing yachts, POS-MY for motor yachts, and POS-KY for ketch/yawl rigs.

The STV 312/4 SY is designed specifically for sailing yachts. For motor yachts, the appropriate navigation light monitoring is available as a separate POS-MY module.
