Made from the larger power supplies that are found in the servers that run large computers, these power supplies are the answer for modelers who need to charge large, 4-10 cell Li-Po batteries quickly at high current levels.  The current crop is capable of delivering 75 amps of highly-regulated 12 volt DC current.  If you need more current than most over-the-counter 12 volt power supplies can provide, this might be your solution.  Our most powerful 12 volt power supply, it can be "ganged" together with a second unit to provide 24 volts @ 75 amps, or more than 1800 watts of power!  Just make sure that the metal cases of the two units are insulated / isolated from each other by a partition of a non-conductive material.


Comes complete with AC power cord.


IMPORTANT NOTE:   These units are heavy, and shipping is higher than normal.  Power supplies will be shipped via U.S. Postal Service Priority Mail Flat Rate at the least expensive rate possible.

12 volt 75 Amp/900 watt DC Power Supply

  • Like our other units, these are built from re-cycled computer power supplies, and are rugged and almost indestructible.  They feature short circuit protection, thermal and overload protection, and deliver a smooth, regulated 12 volts that's perfect for battery chargers.  If shorted, the output simply shuts down before damage can occur. Just turn the unit off, wait a few seconds, and turn it back on again.  It's that easy, and it doesn't even blow a fuse!  A pair of banana jacks on top provides a convenient connection to almost any standard battery charger, and a switch allows you to turn the unit on/off without unplugging the AC power cord (included).   If you need to connect more than one charger at a time, consider using one of our 12 volt Power Distribution Boxes, or you can replace the banana plugs on your charger with a pair of ours that will stack or daisy-chain together for multiple connections.


    These units have a pair of high-output fans mounted in the front panel to provide the cooling needed for high current demands, so they tend to be a bit noisier than a traditional power supply, but since heat is the #1 enemy of anything electronic, you probably won't mind the extra noise.  (The fans in this unit do not run all the time, only when the unit is turned "on".)
