Instruction manual
DESCRIPTION
PSV 2415-12 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 2415-12 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 system for 24 V installations
 Distributed power supply systems with built-in redundancy
 Power supply systems for access control, fire and intruder
alarm installations

MAIN FEATURES
 Security grade 3 (EN 50131-6:2008)
 Type A – mains supply with rechargeable battery
 Total rated output in grade 3:
 0.25 A (30 h in battery mode with 12 Ah batteries)
 Total rated output in grade 2:
 0.74 A (12 h in battery mode with 12 Ah batteries)
 Total rated maximal output to installation: 1.0 A
 Battery recharging current – 0.5 A, providing recharging time
below 24 h
 Total current capacity of power unit – 27.6V, 1.5 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 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)
 Remote and local battery testing
 Tamper security provided – case opening and pry-off
