    200 Watt DC-DC PSU

    Just hooked up one of these bad boys, we'll see how well it works when I get it next week.

    Does that need to be regulated, or do you think it works straight out the box?

    The auction says

    Input: 10.5 - 15v DC.
    Output 200watts @ 12v DC.
    Approx. 16 amps draw at full power!

    if it takes an input of 10.5 - 15v DC I'm guessing it has a regulator built right in. I'll post a full review of it once I get it and install my system.

    The EBay ad says 10.5 to 15 volts input, so i would say no that it doesn't have to be regulated. Pretty impressive tho. I bet that baby gets hot considering how small and the amount of heat it dissipates (200W !!).

    Let us know about this.

    Reality check: What do you think will happen to the flimsy little power connector and wires on the input side if you draw 16A through it? I don't think it will last very long..

    What will happen is nothing. We're talking 16A not 100A. I know a few who have bought from audioforge the P120/A and they seem happy with it so hopefully this lives up to the name.
    Mine needs to be updated.

    16A is enough to power a small industrial hydraulic motor. I just replaced a switch that was rated for 16A and the thing was burnt up to a crisp. Just make sure you keep the thing cool or you may need to break out the fire extinguisher.

    Extremely small motor, I guess.

    My best guess from the pic is 14AWG wire. That should be adequate for 16A@12VDC.

    But that coaxial connector has got to go. Anderson powerpole is the defacto standard for secure high current connection as far as I'm concerned.

    No, I don't work for either company.

    I just ordered one of these DC-DC supplies also. Looks like a great product to replace my weak ITPS/PW70a. We'll see...
