Shuttle offers a wide range of optional accessory products for its box PCs. By default, the box PC is powered via the supplied external power supply unit with a 19-V operating voltage, where the 5.5/2.5-mm power connection of the adapter is connected to the DC input of the box PC. With the optional VOL01 accessory, the permissible operating voltage is extended to 9 - 36 V DC, so that other voltage sources (e.g. 12 V or 24 V) can also be used. The box PC BPCAL02 can also be equipped with the optional accessory PDC11 if a fixed screw connection is required to connect the cables of an external power supply and an external power button.
