High Power 48V battery chargers with very low noise for marine, display room, and trade
shows |
|
|
|
|
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.
Suggested Applications: Wherever
a high power 48 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. and 48V output).
 These
chargers are the famous APS power supply with a charging circuit built-in. This charge controller 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-CH 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.
The PST-APS-CH
power 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 chargers were originally designed to power automobile audio systems in demonstration rooms and trade shows. They have
very low ripple and no audio noise. Other output voltages can be made upon request.

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 battery is full the charger goes into a maintanence mode. In maintenance
mode the battery is safely floated at 54.2 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.
