Intelligent power distribution meets smart heating control

Products10. July 2025 by Hannes Büttner - Reading Time 2 min.

E-T-A’s MRV (Marine & Recreational Vehicles) division is looking forward to this year's Caravan Salon in Düsseldorf - the international industry meeting place for everything to do with mobile travelling. The E-BOX, our innovative all-in-one power distribution system for mobile homes, will take centre stage at the 2025 trade fair. The presentation is complemented by a new co-operation with Webasto in the area of heating controls.

E-BOX: compact and clever design, increased productivity

With the E-BOX, E-T-A presents the world's first all-in-one power distribution system with charging and booster function - a genuine plug & play solution that revolutionises both the technology and production processes. I Individual components such as charging unit, charging booster, AC distribution unit, RCD, DC distribution unit and fuses are integrated into a single device.

Manufacturers benefit from significant time savings, reduced complexity and less rework. The clear structure allows fast and error-free mounting - perfectly suitable for series production. For service companies and end customers, this means maximum operational safety, tank level visibility and long-term reliability.

New: Integration of Webasto heating solutions

As part of our new partnership with Webasto, the E-BOX will also serve as the central control unit for heaters like the new Air Top Pro 25 (air heater) and the Thermo Top Evo Smart (water heater). Communication takes place via the standard LIN interface. This allows users to control the heating functions from the E-BOX fully graphic display.

A real game changer

This combination of sophisticated power distribution and intelligent heating control takes on-board electrical systems in mobile homes to a new level. Manufacturers can rely on a standardised system that not only decreases assembly times, but also significantly increases customer benefits.

The first contact with Salty Blue Camper, a specialist in campervan conversions, was also made at the Caravan Salon in 2022. The company is now a loyal customer and long-term partner of E-T-A and relies on our E-BOX (click here for the interview with Salty Blue).

Perhaps your success story and our co-operation will also begin with a visit to our stand at the Caravan Salon!
