The following table describes the
display of LED lights at different stages of charging:
Q: Can I leave
the battery continuously on the charger?
A: Yes, the charger will go
into "maintenance mode" and keep the battery topped off.
Q: Can I draw
power from the battery when the charger is connected?
A: Probably. . .
There is some pulsing going on with the charger which your equipment might not
be happy with (it is a pulse-charger, 1 second pulses with 20mS gaps), but if
you combine this with the battery the battery will fill in the gaps, so the
ripple is no more than it would see in an automotive application.
Q: If I
discharge the battery while the charger is attached will the charger maintain a
full charge?
A: Yes, When the charger detects that the battery voltage
has dropped it knows that the battery needs to be charged and goes into "bulk
charge" mode again automatically.
Q: Can the charger be left connected to
the battery when the charger is not turned on, or when the input voltage of the
charger has been cut off?
A: Yes.
Applications:
Charging lighting system batteries, and scooters in a 48Volt
telecommunications, train, locomotive, boat, or electric vehicle.
Fully automatic without intervention.
Output short circuit and battery polarity protections. Input low voltage and
high voltage connections.
Charging 24 volt electric bicycle from a 48V golf cart, telecommunication
system or locomotive.
Three stage charge--constant current, constant voltage, and float. It is
suitable for any size 24 volt lead acid battery.
Installation
Notes:
- A qualified automotive electrical technician should be used
to wire the charger into the vehicle.
- The PBCD315-48-24 converts 48 volt power into 24 volt power
with 75% efficiency, so for a 10 amp output the input needs over 4.4 amps. Make
sure that the wires connecting the are adequate for the current and the length
of the run. If the voltage drop in the wires are too much the "Low Battery
Voltage" alarm will come on. Wires that are too small may also overheat and
melt the insulation, causing a dangerous situation. 12 gauge is usually
adequate for runs up to 20 feet of wire (adding together the positive and
negative wire lengths).
- It is OK to leave the unit on the charger when the power to
the charger goes on and off.
- Mount in an area that will get adequate ventilation and will
be free from rain, spray, or excessive dust.
