DC Power Supply for Triton Charger?


I am veryinterested in the Triton Bwttery Charger from Great Planes for its fantastic versatility and wide range of batteries it is capable of charging. However, it is DC powered and I would want to enhance its use at home. Has anyone been successful in using a DC power supply running off 100 VAC to power this charger? Any recommendations??

Thanks in advance for any replies!

I am running my Triton at home from a converted computer power supply. Works like a charm! There is a website where I got the instructions from. I'm at work right now and don't have the link, but I will post it when I get home in a couple of hours.

I just built one from the instructions from RCBATTERY clinic. Cost $4.00, I bought the plug in posts and the socket for the 1157 light bulb from Radio Shack. I didn't like the screw and washer instructions for hooking up the charger. I don't like anything that clips on, to easy to short out and cause problems. The light bulb also tells you that the power supply is turned on, I didn't use the resistor.

I also used the light bulb. It's a great indicator that the power supply is on. And I put a pair of jacks on instead of the exposed posts, too. Easier, and I think safer, too. I also didn't like the idea of the exposed post becasue it would be too easy to short them.

I'm using one of the supplies Mike pointed but added a little. You can take a look at the project here: https://www.rcgroups.com/forums/show...t=power+supply

It only took an evening to put together.

I don't think your 10A power supply from Hobby-Lobby is the same as the 13 amp supplies from http://ramboy.com/cosel.htm, but your box project does looks nice.

The web site warns that those Cosel power supplies will be sold out soon.

nope, not the same, but close enough. Just make sure the physical dimensions are the same.

If you want a nice quiet dc power supply that will even run 2 chargers at once if necessary, take a look at the 25amp unit from radio shack. I have owned mine for about a year and it is whisper quiet and built very well. Picked mine up for $59.

Which way is up?
I'm using a 10a power supply from Radio Shack. Probably over a year old and runs fine. I power 2 or 3 chargers at a time with it (unless the packs are over 10 cells, then have to drop to 2 chargers).

I agree with the Radio Shack power supply.
I tried the PC Power supply but it didn't work for when I wanted to charge the transmitter pack at a fast charge.

Is that a Radio Shack enclosure that you put the Cosel in?

I ordered one but would like to do something to protect the AC lines.

Thanks,

Cosel Power Supply Enclosure


Here is what I did to enclose the wire strip of the Cosel power Supply. The enclosure is from Radio Shack part number 270-283A called Project Enclosure with PC board. The cost was under $4.00. I drilled holes for rubber grommets and drilled out the upper holes to accommodate sheet metal screws. I then cut out the lower ones with hobby knife to get more room for the wires. It fits perfect and by having it installed along the right edge you can see the "on" light. Didn't plan for it, but it worked out thay way. I didn't install lower sheet metal screws because it is tight enough wthout them. I hacked up an outdoor power cord with ground rated for 10 Amps. I didn't need the PC board, just the enclosure.

Good charging,

Ed
