EATURES
High efficiency cost effective power supply suitable for use in systems designed to comply with
PD6662:2017 and EN50131-6:2017 Grade 3 and Environmental Class II. Rated to provide continuous
current to load for systems requiring 12h standby from a battery. Three independent output signals
are provided for loss of mains fault (EPS**), battery fault (APS**), and power supply fault (GEN).
Comprehensive self-diagnostics can detect blown output and battery fuses, battery fail, low battery
voltage, battery missing and low output voltage. The PSU incorporates intelligent battery
management comprising active full load battery testing, 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 or 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.
