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 maximum 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 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 temperature.
In case of mains voltage failure, batteries are automatically switched to the load without any interruptions.
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 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 to the alarm control panel, along with a RS232 port for the connection to the configuration program Test-PUA009.
Hot-swapping is possible for both the 4 AC/DC converters and the battery charger (Hot Plug).
