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.
