PLN‑24CH12 24 V and PRS‑48CH12 48 V
Battery Chargers
The PLN‑24CH12 and PRS‑48CH12 Battery Chargers are
designed for public address and emergency sound
systems, to assure that the system batteries are always
charged. Rack mountable, the unit charges lead‑acid
batteries and simultaneously provides 24 V or 48 V for
system components that use 24 V or 48 V exclusively.
These chargers are fully compliant and certified to
EN 54‑4. The battery chargers are premium quality,
intelligent, microprocessor controlled devices.
Functions
Performance
The maximum charger current is 12 A for charging the
battery. The maximum battery capacity, according to
EN 54‑4, is therefore 225 Ah, minimum size is 86 Ah. The
maximum output of the back‑up power system is 150 A.
The charger has an input voltage range of 195 V to 264 V,
and a power factor corrector. The charger features
automatic shutoff when the battery voltage is too low, to
prevent battery damage. It also features over‑voltage
protection, protection against wrong battery polarity and
short‑circuit protection. The outputs are protected by
fuses. The power supply takes a resistance measurement
of the battery including connections every 4 hours.
The charger comes with a temperature sensor that is used
to adjust the charging voltages.
▶ 12 A battery charger
▶ 6x 40 A, 3x 5 A outputs
▶ 150 A back‑up current
▶ Fully supervised, EN 54‑4 certified
▶ Under‑voltage and over‑voltage protection
The charger has additional 24 V or 48 V (depending on
model) auxiliary outputs, to supply power to equipment
that needs 24 V or 48 V as primary power. The current
capacity of these outputs is 5 A per output.
The charger has relay outputs to signal a mains fault,
battery fault and charger output voltage fault.
