2.1.4 S81-PU002 Power Supply Set
This power supply set is able to supply a maximum current of 32 amperes, duplicated to the load,
and to control and charge two 12 Volt batteries with maximum capacity of 120Ah. Battery maxi-
mum charge current is 6 amperes. Under normal operating conditions, a simplified test is carried
out every 30 seconds in order to check the proper presence of the batteries. A full test, instead, is
carried out every hour in order to check electrical connections and battery efficiency. During bat-
tery trickle charge, battery voltage is compensated automatically according to the temperature. In
case of mains voltage failure, batteries are automatically switched to the load without any interrup-
tions. Should the full charge stage exceed 24 hours, the power supply unit will signal a battery fault.
In case of primary power supply failure, the system will shut batteries down when the on-load volt-
age is lower than 18VDC in order to avoid damaging the batteries. The set features seven open col-
lector outputs for replicating the various types of faults to the alarm control panel, along with a
RS232 port for the connection to the configuration program Test-PUA009. Ho-swapping is possi-
ble for both the 4 AC/DC converters and the battery charger (Hot Plug).
