Instruction manual
PSV 24100-12
DESCRIPTION
PSV 24100-12 is an up-to date power supply unit with battery
backup compliant with EN standards. Unit provides all features
required by EN 50131-6:2008, security
grade 3
.
Distinctive and unique feature of PSV 24100-12 is invented by
Alarmtech ViP mode
–
Voltage-in-Parallel. Power supply units
with ViP feature can be connected in parallel both (+) and (-) on
one common power bus without a need of additional synchroni-
zation. 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 compensate voltage drops on a bus by placing
power supply units in distant bus sections.
Power conversion is based on high frequency SMPS regulator
providing high conversion efficiency. Low losses inside unit pre-
serve batteries from overheating shortening battery life time.
Computerized battery recharging circuit works in constant poten-
tial
–
limited current mode
–
the best mode to provide the longest
possible battery life time.
Power unit is equipped with built-in diagnostic system detecting
and signalling mains failure, different battery failures including
end-of-life warning, output faults like low voltage or broken fuse.
