Digital Power Distribution & Switching Module for Vehicles, Campers, and Boats
The PSU Switching Unit 9012-8 ADV from philippi is a digital switching module with integrated electronic fuse protection for the electrical system of vehicles, campers, and boats. It replaces relays, fuses, and power distributors with a single, freely programmable unit featuring 8 inputs, 8 outputs, and a total current of 90 amps.
- One device instead of many individual parts: completely replaces relays, thermal fuses, and distribution blocks
- Less wiring and installation time, as all power distribution is centralized
- Customizable via software instead of hardware – changes without fuse replacement or re-wiring
- Directly control motors, pumps, and valves via the integrated H-bridge
- Electronic fuse protection per output – additional fuses are not necessary
What the PSU Replaces
Instead of many individual relays, thermal fuses, and distribution blocks, one device handles the complete power distribution and protection of your onboard electrical system. This saves space, wiring, and installation time – and makes your system adaptable via software, instead of having to swap out hardware.
Functions at a Glance
- Electronic fuse protection per output – no additional fuses needed
- Relay functions: flashing, dimming, and timer control
- Individual battery protection per output – optionally time- or voltage-controlled
- Rule-based logic functions for intelligent switching sequences
- Motor, valve, and pump control via the integrated H-bridge (e.g., electric steps)
- Master light and panic function for maximum control and safety
- Individual programming of all inputs and outputs
Current & Protection
Each output is digitally protected and can handle up to 25 A per channel; the current limit is flexibly adjustable in 5 A increments. This allows you to precisely match each circuit to its consumer – without changing fuses.
Operation & Expansion
The outputs can be controlled via various signal types: classic switches, digital signals, or analog input signals – freely configurable and automatically synchronized. Multiple PSU units can be operated in series or in parallel to flexibly expand the system.
Areas of Application
- RV & Camper: dimming lights, centrally switching and protecting cool boxes, pumps, and consumers
- Boat & Yacht: robust onboard power distribution for demanding marine applications
- Vehicle, Off-road & Special Vehicles: directly controlling motors, valves, and steps
Example Configuration
| Output | Standard 1 | Individual |
|---|---|---|
