Summary:
Batteries are not very susceptible to ripple and noise, so many high power
battery chargers have limited filtering and put out 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. This line
of 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 DLS
power supplies with 48V taper charging. The optional APS-IQ4 charge controller
allows the DLS charger 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.
Ideally suited for the 48V
telecommunication systems. The power supplies feature regulated and filtered
outputs which allow for clean power busses without the slightest hint of
noise.
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. This is a switchmode design using frequencies
beyond that of human hearing, there is no low frequency transformer hum. The
cooling fan is virtually silent.
The PST-DLS 48V 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 DLS power chargers has 86% efficiency. This superior
design results in cooler operating temperatures and compact size.

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 48 volt battery is full the
charger goes into a maintenance 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 plates of the battery and avoiding
stratification of flooded batteries.
