72V input DC/DC battery chargers, for 12V and 24V batteries for Locomotives

DC/DC battery chargers  6 volt batteries from a 12 volt source,  72V/12V

For More DC/DC battery chargers, 24V to 12V, 12V to 24V, 24V to 24V, 72V to 12V

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 charge 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.

Universal Power Input OEM Power Supplies and OEM Battery Chargers Taper charge--constant current, constant voltage, and float. .

Installation Notes:
  1. A qualified automotive electrical technician should be used to wire the charger into the vehicle.
  2. 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).
  3. It is OK to leave the unit on the charger when the power to the charger goes on and off.
  4. Mount in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.
