Digital Switching.
Digital switching means that lights and loads are switched, dimmed and protected electronically instead of through individual relays and fuses. At philippi this is done by the PSU Switching Unit 9012-8 ADV with 8 outputs up to 25 A and 90 A total current. With the PCU Control Unit you operate every lighting group on the display.

Switching and dimming lights with the PSU
The PSU dims lighting, switches loads and drives motors, pumps and valves via the integrated H-bridge. Master light and panic functions switch all lights together. Each output is electronically protected and adjustable up to 25 A in 5 A steps. The PSU also runs without a display, via push buttons and switches; with the PCU you also see the current of every output.

Digital switching with P-BUS
With the P-BUS, individual cables no longer run from the switch to the load: the CMR relay modules sit close to the loads, switch, protect and dim LED lights. They are operated from the PSM3 and PSL system monitors. Added to this are the PCU Control Unit, main switch components and the PSU Switching Unit.
In short: Choose the relay module by current and number of poles: CMR 811 S and CMR 411 S switch single-pole up to 10 A per channel, CMR 431 S single-pole up to 30 A, CMR 412 S double-pole up to 10 A and CMR 232 S double-pole up to 30 A.
The range
| Relay module | Channels | Current per channel | PWM dimmer |
|---|---|---|---|
| CMR 411 S | 4, single-pole | 10 A | 4 |
| CMR 811 S | 8, single-pole | 10 A | 4 |
| CMR 431 S | 4, single-pole | 30 A | – |
| CMR 412 S | 4, double-pole | 10 A | 4 |
| CMR 232 S | 2, double-pole | 30 A | – |
- CMR relay modules: each available with fuses or with circuit breakers. In emergency mode, every output can be bridged by re-plugging, and the protection is retained.
- Operating and displaying: P-BUS System Monitor PSM3 with 3.5-inch touchscreen, PSL and PSL Plus with 5-inch touchscreen, the PSL Plus with connections for up to four tank senders; philippi Control Unit PCU with or without frame.
- Main switches and energy: FHC 265 remote-controlled circuit breaker with under- and overvoltage protection, TSC main switch interface for the external FBR 500 disconnect switch with 500 A, EM-Box V3 energy management for 24 V systems with up to three battery groups.
- Digital power distribution: PSU Switching Unit 9012-8 ADV with 8 inputs, 8 outputs, electronic protection and 90 A total current.
You register the P-BUS devices directly on the monitor, without an additional computer. All compatible components are shown on the page P-BUS compatible devices; structure and termination are explained in the article Understanding the P-Bus.
Frequently asked questions. Answered briefly.
What does digital switching mean at philippi?
Lights and loads are switched, dimmed and protected electronically instead of through individual relays, fuses and long cable runs. In one device this is done by the PSU Switching Unit 9012-8 ADV with eight outputs, operated via push buttons or on the PCU Control Unit. For distributed systems there is the P-BUS with CMR relay modules and the PSL and PSM3 system monitors.
Can I dim LED lighting digitally?
Yes. The PSU Switching Unit 9012-8 ADV dims lighting directly: in the standard configuration, outputs 1 to 4 are set up as dimmers with 10 A each, and on the PCU you set every lighting group to the exact percentage. In the P-BUS, the CMR 411 S, CMR 412 S and CMR 811 S relay modules each have four PWM channels for dimmable LED lights.
Do I need a display for the PSU?
No. The PSU works independently of the display: via its eight inputs you operate every output with conventional push buttons and switches. The PCU Control Unit adds operation on the display and shows the current of each output. Push buttons, switches and display are synchronised automatically.
Does the PSU replace fuses and relays?
Yes. The PSU replaces individual relays, fuses and distribution blocks with one programmable unit. Each of the eight outputs is electronically protected, and you choose the value in 5 A steps to suit the load. You make changes in software, without changing fuses or rewiring. Several PSUs can be run in series or in parallel.
Which CMR relay module suits my loads?
The CMR 411 S switches four single-pole circuits up to 10 A, the CMR 811 S eight. The CMR 412 S switches four two-pole circuits up to 10 A. For higher currents, the CMR 431 S has four single-pole and the CMR 232 S two two-pole circuits up to 30 A. Decisive are number, current and poles.
What happens if the P-BUS system fails?
Every output channel of the CMR relay modules remains usable. By repositioning the fuse or circuit breaker, the circuit is bridged manually in emergency mode, while the protection is retained. For this purpose the modules are available with either ATO fuses or circuit breakers. Lights, pumps and other loads can therefore continue to be operated.
Can high-current loads also be switched digitally?
Yes. The remote-controlled FHC 265 P-Bus power switch switches high-current loads such as a windlass, bow thruster or inverter via an external push-button or the P-BUS and has adjustable under- and overvoltage protection. The TSC main switch interface controls the FBR 500 battery disconnect switch with 500 A. Settings are made on the PSM3 or PSL.
