18.2 Power Cabinet and Power Units
AutroSafe 4 provides the following power cabinet and power units:
• Power Cabinet BP-405 (obsolete)
• Power Unit BPS-405 (obsolete)
18.2.1 Power Cabinet BP-405 (OBSOLETE)
The Power Cabinet BP-405 contains the following:
• 24V/5A power supply (BPS-405, Meanwell Power Supply)
• Power Board BSF-400, including:
o AutroFieldBus interface
o 115VAC /230VAC input
o 6 outputs 24VDC (max. 2A each)
o 1 fault relay output
• 2x12V, 18Ah batteries
For detailed information, refer to this chapter (Power Supply) and
datasheet.
18.2.2 Power Unit BPS-405 (OBSOLETE)
The Power Unit BPS-405 contains the following:
• 24V/5A power supply
• Power Board BSF-400, including:
o AutroFieldBus interface
o 115VAC /230VAC input
o 6 outputs 24VDC (max. 2A each)
o 1 fault relay output
For detailed information, refer to this chapter (Power Supply) and
datasheet.
The inputs for the battery and the charger are specified to handle up to
10A. The fuses, F7 battery and F8 Charger, shall have 10A fuses.
Batteries that are to be used with BSF-400 are Fiamm batteries with the
maximum size of 18Ah. The minimum size of batteries if batteries are
connected is 7,2Ah.
The maximum current that may be drawn from the batteries when the
primary power source is disconnected is 10A for BPS-405.
There is no minimum requirement for drawing power. The maximum
power that may be drawn from BPS-405 is 3A.

The maximum internal resistance for a battery connected to a BSF-400
is 0,8, any higher resistance than this will be detected as a fault in the
battery by BSF-400.
NOTE: If power to the system is supplied exclusively from the batteries
(in case of a power supply failure), and the voltage is below 19V, the
Power Board BSF-400 will perform a controlled shutdown (i.e. the
power is switched OFF).
