And linear is not as efficient, but far more tolerant of surges. What did they want for it? I'm currently running on a 28 volt switcher good for 12.5 amps if actively cooled. 42 volt rated drivers, so I would like to locate a higher voltage (36?)supply. OTOH, I've only $30 from All Electronics in this one, which also has 5 and 12 volt outputs at logic circuit currents. They are live full time but the main output is switchable, medical grade stuffs they claim. > 3 - http://www.probotix.com/index.php?view=product&path=14&product_id=51 > # 280 Oz In.

Running at 2.4 amps, could raise that 1 notch I think. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
