[ARC5] Cool New DC-DC Converter

[Brian]

Hello Scott,

Where did you get this idea that power supplies share their output loads?
Doesn't apply to any SMPSU I know, nor to any rotary supplies either.

Folks,

Cold heaters take about twice as much as when warm. But, there's no B+ 
drain then, so the supply can direct all its primary power capability to 
the heater circuit. Most of these are power limited at about 1.3 times 
the rating so:12V 3A is 36W + 60 mA x 520V = 25W makes a total power 
limit of 61W. If all that is directed to a 12V heater circuit, you could 
get 5A, or 10A for 6V. I'm not sure the 10A would actually work bu the 
12V 5A ought to.

Someone needs to buy one and see what it actually does.

Happy glowing,
