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 24 Volt wheel chairs,
bicycles, and scooters in 24V and 36V systems.
Fully automatic without
intervention.
Output short circuit and battery
polarity protections. Input low voltage and high voltage connections.
Charging 24 volt batteries from a 24V
or 36V vehicle.
Charging 24 volt trolling motor
batteries from a 24V or 36V boat.
Four stage
charge--constant current, constant voltage, fill, and float. This charges your battery the
fastest way possible without damaging the battery. 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 PBCD180-24-24 converts 24 volt or 36 volt power into 24 volt power, so for a 7.5
amp output the input needs over 8.3 amps. Make sure that the wires connecting the charger 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).
- PowerStream can supply the connector that fits into many wheelchairs (
we have the 3 pin
XLR style in stock
). Consult the manufacturer or a wheel chair technician to obtain the proper cable and
plug. (If you know about such things please educate us!)
- It is OK to leave the unit on the charger when the power to the charger goes on and
off.
- Mount the charger in an area that will get adequate ventilation and will be free from rain,
spray, or excessive dust.
