Some desktop printers like the HP used to have a separate 30V wall wart. Perhaps you could source one of these on a scrap heap somewhere?Well, after digging back through datasheets, it turns out that this particular set of solenoids are rated as 27V, not 12V, like every other supplier advertises.
At 27V, I should get about .5 lbs of oomph, so I figure I might try 32-36V.
With that kind of voltage, should I still be looking at wall warts? I know this higher voltage range gets pricey; is there any circuitry that can boost 24V 500mA to a higher voltage?
