| PST-APS-100 |
Summary: Most high power battery chargers have
significant 60 or 120 Hz ripple and noise. Others used pulse charging
technology. This causes havoc with systems such as audio systems that would
like a nice, clean voltage. These chargers are designed to charge a battery at
high power, but very quietly. Charge lead acid, SLA, sealed lead acid, Gel, AGM
and VRLA batteries
Suggested Applications: Wherever a high power
12 volt battery charger is used, for example in in Audio Displays, Demo &
Show Vehicles Marine & Recreational Vehicles; Battery maintenance &
storage, Retail Store Displays, Industrial Applications, Communications
(available in 12V ,
36V .
42V . and
48V output).
 These chargers are the famous APS
power supply which will charge a battery using the taper charge method. Also
available is a charge controller which allows the APS Power Supply to operate
as an automatic 3-stage “smart charger.” This gives a sophisticated
charger with Bulk, Absorption, and Float stage charging, increasing the
charging capacity of the APS Power Supply to decrease charge times, insuring
proper and safe battery charging and eliminating over-charge. This
“intelligent” technology monitors the battery at all times.
These AC input switchmode chargers are ideally suited
for the mobile environment. These power supplies feature regulated and filtered
outputs which allow for clean audio demonstrations without the slightest hint
of noise.
Their low profile design allows for convenient mounting
under a display vehicle or behind a display board. When combined with a high
quality battery, APS units can supply transient surges up to 1000 amps.
In maintenance mode the charger is left connected to
the battery. If the voltage remains in the long term stage for more than seven
days, the charge controller will automatically deliver a boost charge for a
short time, then automatically return to the normal float stage to prevent
sulfation.
Virtually Silent Operation. All
PST-APS 12V chargers utilize an advanced switching design. There is no low
frequency transformer hum. Every unit is equipped with a cooling fan that is
virtually silent and does not usually come on.
The PST-APS 12VDC battery chargers all feature thermal
control circuitry that engages the fan only when internal temperatures require
it (typically 75% of full load). They have small compact sizes compared to the
transformer based power chargers. The switch mode technology utilized in APS
power chargers has 86% efficiency. This superior design results in cooler
operating temperatures and compact size.
These 12 volt battery chargers were originally designed
and are widely used to power automobile audio systems in retail demonstration
rooms and trade shows. They have very low ripple and no audio noise. Other
output voltages can be made upon request.

A
taper charger is a constant current charger up to the float voltage, at which
the current tapers off until the battery is full. The 3-stage charger keeps the
current constant by raising the voltage until the battery is full, then cuts
back to the float voltage.

Usage Note: Typical AC outlets are 1540VA,
14 amp service. To run the higher power units you will need higher power
service than is typically available in a wall plug. Please consult competent
technical authorities to determine the total load on the circuit you intend to
supply the power with, including other things plugged into the same
circuit.
Maintenance mode: After the 12V battery is full the
charger goes into a maintenance mode. In maintenance mode the battery is safely
floated at 13.56 volts to maintain the battery and replace charge lost due to
leakage or self discharge. In addition, if the battery has not received a bulk
charge during a seven-day period, the charge controller will switch the APS
Power Supply into a pre-programmed equalization stage to top off the batteries,
dissolving any sulfate layer on the battery’s plates and avoiding
stratification of flooded batteries.
Audio Application Note:
Operating high power audio systems from the battery while it is on charge can
cause the charger to change charge stages at random, which you might be able to
hear. If you are running equipment from the battery while the charger is
attached you can remove the jumper plug from the charger, which will revert it
to a 13.6 volt power supply to give you better sound. Just plug it back in to
make it a multistage charger.
To perform this function remotely put a
toggle switch in the jumper as follows
