14 circuits plus full P-Bus monitoring instead of pure battery monitoring? The STV 256 is equipped with the PSM3 system monitor and also offers navigation light monitoring and a USB-C/A charging socket.
The PSM3 System Monitor
Unlike the BTM2 in the STV 236, the PSM3 is designed for integration into the complete P-Bus network – central display for battery, tank, and on-board power status.
Compared to STV 236 and STV 274
If pure battery/tank monitoring is sufficient for you, the STV 236 (BTM2) is more affordable. If you want the largest display, the STV 274 (PSL) is the alternative.
