Power Supply - was Triton

[Larry Ott]

I just bought the 18 amp version: a Pyramid PS21KX here:

http://store.yahoo.com/bsless/ps21kx.html

It says 10 amp at the top but it states 18 in the text.
Best part is only $61 + $10 shipping

They also sell the other models for less than millionbuy.com

    I purchased a Pyramid 10 Amp Power Supply (PS15KX) for $39.95 from
MillionBuy.com. The version I got has banana plugs and a cigarette lighter
attachment. For $5 less you can get a 10 Amp version without the cigarette
lighter attachment.

    This is a really good price, and Pyramid is a top notch brand.

    The following web link has power supplies ranging from 2.5 Amps to 40
Amps. I would recommend this product. I personally would not use a PC power
supply.

    On the charger discussion, I use a Dymond Super Turbo and have been
happy with it, it is also very competitively priced. If I were to buy one
now I would go with the or Schulze 6330 which can be purchased from
RC-Direct.com. This model has a serial output for a PC but they have a
cheaper version without this feature. Pretty sure it works with Lithium Ion
too. It's an awesome charger and is used buy many of the high end electric
guys, especially in Europe. It's may be overkill for our application, but as
stated earlier, we've got a lot riding on our batteries.

      I don't use the charger but I have considered it if/when I need to
replace my Simprop charger (similar to SuperNova).


      As for power supplies, I would recommend at least a good 12V 10A bench
supply, they are about $50 from Parts Express (www.partsexpress.com). I know
a lot of people use surplus computer power supplies. If you do, make sure
the 12V output is up to the needs of your charger. If you plan on charging
high capacity packs with cell counts of 8 or more, the chargers internal
circuitry will draw more current from the power supply than the charge rate
setting. Example: An 10 cell 3000mAH NiMH pack peaks at 18 volts or so. Lets
say you are kind to your batteries and charge at a 3000mAH rate. Using V x A
to calculate watts,  3000mAH X 18 volts = 54 Watts of power going to the
battery. The charger will have to draw that much power from the supply (+ a
little more to run itself) so 54W/12v=4.5 amps drawn from the supply. A 10
amp rating should be enough to handle two chargers simultaneously for most
charging needs.

        Is anyone on the list using the Great Planes Triton
Charger/Analyzer?
        If so what is your opinion of it?

        What are you using for a power supply?
