Instruction manual

DESCRIPTION

PSV 1215-18 is an up-to date power supply unit with bat-
tery backup compliant with EN regulations for social and
security alarm systems. Unit provides all features required
by EN 50131-6:2008, security grade 2 and many others
available in grade 3 only.
Distinctive and unique feature of PSV 1215-18 is invented
by Alarmtech ViP mode – Voltage-in-Parallel. Power sup-
ply units with ViP feature can be connected in parallel both
(+) and (-) on one common power bus without a need of
additional synchronization. Connected units will share
load on a bus. ViP feature can be used to build distributed
and redundant power systems. It can be also used to com-
pensate voltage drops on a bus by placing power supply
units in distant bus sections.
Power conversion is based on high frequency SMPS regu-
lator providing high conversion efficiency. Low losses in-
side unit preserve batteries from overheating shortening
Battery life time. Computerized battery recharging circuit
works in constant current – limited voltage mode – the
most advanced and the best mode to provide the longest
possible battery life time.
Power unit is equipped with built-in diagnostic system de-
tecting and signalling mains failure, different battery fail-
ures including end-of-life warning, output faults like low
voltage or broken fuse.
