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.
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.
