An ultra-quiet DC input lead acid
battery charger with 72 volt input to charge 12 volt and 24 volt batteries
Heavy Duty Industrial, Marine, and Military 12 Volt and 24 volt Battery
Chargers for use in 72V systems, 75 watt. These chargers replace the
PBCD72-72-12 and the PBCD72-72-24. NOTE: A locomotive's 72 volt battery is
really 8 x 8V in series. So the nominal voltage is 64V, and the charging
voltage is 73-76V. So a DC converter with a maximum input voltage of 80V will
work fine.

 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: Yes, this is an advantage of the taper-charge method,
there is no noise from switching between modes, just be sure that there is
enough power in the charger to at least supply the load, then the battery will
take whatever is left over.
Q: If I discharge the battery while the
charger is attached will the charger maintain a full charge?
A:
Yes.
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 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 12 volt "jump start" batteries from a 12 volt locomotive or
float.
Charging 12 volt electric bicycle from a train.
Taper charge--constant current, constant voltage, and float. .
Installation Notes:
- A qualified automotive electrical technician should be used
to wire the charger into the vehicle.
- The PBCH10 converts 72 volt power into 12 volt power with 91%
efficiency, so for a 10 amp output the input needs over 1.9 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.
