    Do these units need any special jumpers to make them operational?

    Every one of these I see sounds like a siren. Nobody cares about noise in a server rack.

    And the RF filtering is not all that good.

    I don't see a spec for the output voltage and current.

    Color me skeptical.

    What about Dell PowerEdge 2800 supply. Does 12v and 75amp.. but Dave's RC says they are clean on scope, (like a battery he said in an email).. cost is $75 flat.

    He said the Dell can't go up any as there is no POT to turn it up inside. I don't even know if the TS500 would run on a flat 12v...

    Or possibly a 57 amp model for $60..?

    Did you have any receiver hash from the powermax charger? Everyone online seems to love them but mine was noisy. I use it as a battery charger now.

    You can tweak It for 13v and they are pretty much rock solid on staying put on a load

    He's got a 57amp model that does 12.33v.. he agreed to what you said, they definitely hold amps and power with no drop out...my only question would be if 12-12.33vDC would cut it with an amp??
