PCU Control Unit – central control and monitoring unit for the vehicle's electrical system

The central control and monitoring unit for your onboard electrical system – in motorhomes, campers, vans and boats

The PCU Control Unit is the central control and monitoring unit for the entire onboard electrical system – the intelligent heart of your power supply in vehicles and on board. You control and monitor your entire onboard electrical system via a single, intuitive touch display: battery, tanks, energy flow and connected devices. Instead of many individual displays, the PCU bundles all functions in one place and gives you full control over the onboard electrical system in your motorhome, camper, van, caravan or boat.

What the PCU replaces

Instead of separate battery monitors, tank gauges and switch panels, a single display takes over the complete control and monitoring of your onboard electrical system. This saves space on the switch panel, reduces wiring and makes operation clear – all values and all controls in one place.

Control and monitor on one display

As a central unit, the PCU combines control and monitoring in one device: You keep an eye on all values and intervene directly – without having to switch between several devices.

Real-time battery monitoring

The PCU provides precise real-time data on battery status, voltage, current flow and temperature and also reliably monitors your starter battery. As a fully fledged battery monitor or battery computer, it displays charge status, consumption and remaining capacity – compatible with 12 V and 24 V systems and all common battery types.

Tank monitoring for fresh, grey and black water

The integrated level indicator monitors all tanks and is compatible with the most common sensor systems – ideal for motorhomes, RVs and boats.

Energy management with energy flow display

The integrated energy flow diagram visualises all sources and consumers in real time – solar system, charge booster, inverter and more. You can see at a glance where the energy comes from, how much is generated and which consumers are active.

Central device control – refrigerator, heater, air conditioning

You can control your refrigerator, heater, air conditioning and other onboard technology directly on the display via CI and CAN bus. Inside and outside temperatures are also displayed.

Easy installation, maximum compatibility

All interfaces are integrated directly into the display – no additional modules are required. In combination with the CONNECT HUB, all sensors are connected centrally, with only a single cable running to the display. Optionally expandable with the Switching Unit (PSU) for a full-fledged load management system.

Made in Germany – developed and manufactured for continuous use on board.

Applications

• Motorhome, Camper & Van: battery, tanks and energy centrally in view – ideal for self-sufficient travel
• Boat & Yacht: robust onboard monitoring and device control for use on board
• Caravan & RV: all consumers and fill levels on one display

Technical data

Frequently Asked Questions

What is the PCU Control Unit? The central control and monitoring unit for the onboard electrical system in motorhomes, campers, vans and boats – battery, tanks, energy flow and devices on a single touch display.

Does the PCU work with 12 V and 24 V? Yes, it is compatible with 12 V and 24 V onboard electrical systems and all common battery types.

Which tanks can the PCU monitor? Fresh, grey and black water via the integrated level indicator, compatible with the most common tank sensors.

Do I need additional modules? No, all interfaces are integrated into the display. With the CONNECT HUB, the sensors are connected centrally.

What is the difference between PCU and a classic battery monitor? A battery monitor only shows battery values. The PCU also monitors tanks and energy flow and controls devices – as a central unit for the entire onboard electrical system.
