Technical Features
2.1.7 PU-A0009-1 Battery Charger Module
Description
This is a UPS able to control and charge two 12 Volt batteries with a maxi-
mum capacity of 120A/h. Battery maximum charge current can be set through
a dip-switch on the module. 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 battery trickle charge,
battery voltage is compensated automatically according to the measured tem-
perature. During the full charge stage, instead, it is kept at 27.6VDC In case of
mains voltage failure, batteries are automatically switched to the load without
any interruptions. Should the full charge stage last more than 24 hours, the
battery charger will signal a battery fault. In case of primary power supply
failure, the system will shut batteries down when the on-load voltage is lower
than 18VDC in order to avoid damaging the batteries. The set features seven
open collector outputs for replicating the various types of faults, several inputs
for monitoring power supply module and cooling fan status, and one RS232
port for the connection to a supervisory system. It is used together with one or
more PU-A0008-1 power supply units. In this case, the resulting power supply
set is fully compliant with the EN54-4:1997/A2:2006 standard.
