The P-Bus Battery Management Shunt SHX 348 is a digital shunt for the P-BUS on-board network that precisely and continuously records the current, voltage, and capacity of a battery – the basis for reliable battery monitoring on board yachts, motorhomes, and off-road vehicles.
- Detects even the smallest currents from 10 mA, with an accuracy of ±0.5% over the entire measuring range
- Calculates the current battery capacity in real time from current and voltage values, displayed in color in the battery symbol of the system monitor
- With a second SHX 348, the starter battery can also be monitored
- Galvanically isolated P-BUS connection – even battery groups separated from the on-board network (e.g., emergency battery for radio equipment) can be monitored
The Philippi SHX 348 is installed in the negative line of the battery and continuously reports current, voltage, and capacity to the P-BUS network. Power is supplied via the existing voltage measurement line; an additional power cable is not necessary. Connection is via an M8 terminal stud, and the P-BUS connection via an M12 connector.
For systems with larger currents or high-power consumers, the identical but more powerful SHX 648 is available.

How accurately does the SHX 348 measure?
The measuring range starts at 10 mA, with an accuracy of ±0.5% – even with a continuous current of up to 300 A.
Can I also monitor my starter battery with it?
Yes. With an additional SHX 348, you can easily monitor the starter battery in addition to the consumer battery.
Can I use it to monitor a battery isolated from the on-board network?
Yes. The galvanically isolated P-BUS connection enables the monitoring of isolated battery groups, e.g., an emergency battery for radio equipment.
Do I need an additional power cable?
No, power is supplied via the existing voltage measurement line.
How high can the current be for a short time?
Briefly, 600 A for 1 minute or 1500 A for 0.5 seconds are permissible, with a continuous current of 300 A.
