hello...

looking to build a simple (read cheap and small) even crude 28v 10amp switch
mode psu to run on 240v in..have liiked on google etc but nothing found..
anyone know of any published designs..thanks simon g0zen..
please reply to group or ..

thanks

On EBay, the Power-One International Series of 24 Volt switchers will handle
wide input ranges. It would just be a matter of tweaking the regulator
detect circuit -- I don't even think it would require adjusting the
compensation. These supplies typically sell for under $40. There is a
power supply section under test and measurement. Cheaper to buy than build.
