F EATURES
High efficiency cost effective power supply suitable for use in systems designed to comply with
PD6662:2010 and EN50131-6:2008 Grade 2 and Environmental Class II requiring 8Ah or 18Ah standby
battery capacity. Two independent output signals are provided for loss of mains fault (EPS**), and
general fault (including APS** fault). Self-diagnostics can detect blown output and battery fuses and
low battery voltage (APS fault). The PSU incorporates a battery management system comprising low
battery voltage detection and deep discharge protection to ensure that the battery is not permanently
damaged through excessive discharge. A brownout filter ensures that short mains voltage dips do not
create a false loss of mains alarm. Two LEDs assist with quick and easy installation by showing
presence of mains, correct battery charging and a fault condition. Comprehensive protection is built-in
as standard including mains transient filtering, electronic output overload protection and fuses on the
load and battery outputs.

O PERATING I NSTRUCTIONS
In the event of loss of mains, a battery fault or a GEN fault, the corresponding Fault signal contacts will open.
If the output of the PSU fails, the cause of the failure should be investigated e.g. short circuit load,
connection of a deeply discharged battery. The fault should be rectified before restoring power to the PSU. If
any of the fuses require replacing, ensure the correct fuse rating and type is used.
M AINTENANCE
Maintenance
This unit is intended for use by Service Personnel only. There are NO USER SERVICEABLE parts inside.
There is no regular maintenance required of the PSU other than periodic testing, and replacement of the
standby battery. Reference should be made to the battery manufacturer's documentation to determine
typical/expected battery life with a view to periodic replacement of the battery.
