Power Supplies
24 VDC/10 A
Battery 12 Ah/Security grade 3
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.
APPLICATIONS
•Power supply systems for access control, fire and intruder
alarm installations with security grade 3
•Distributed power supply systems with built-in redundancy
for 24 installations
MAIN FEATURES
•Security grade 3 (EN 50131-6:2008)
•Type A –mains supply with rechargeable battery
•Basic parameters in grade 3:
➢Total rated output: 0.2 A
(30 h in battery mode with 12 Ah batteries)
➢Battery recharging current: 0.5 A
(providing recharging time below 24 h)
➢Total rated maximal output to installation: 9.4 A
•Total current capacity of power unit –27.6V, 10 A
•ViP (Voltage-in-Parallel) feature increasing reliability and ca-
pacity of power supply systems –power supplies with ViP fea-
ture can be connected in parallel to same bus without need
for additional synchronization
•Capable to work with a pack of two 12 V/12 Ah sealed lead
acid batteries
•Short circuit and overload protection
•Detection of no mains supply (EPS fault)
•Detection of different battery faults (APS fault) –not con-
nected, low voltage, high internal resistance
•Detection of low output voltage (OUT fault)
•Detection and LED identification of broken fuses
•Detection of power unit failure
•Deep discharge protection of battery (DDP)
•Built-in high voltage protection circuit
•Remote and local battery testing
•Tamper security provided –case opening and pry-off
