hello guys
i am planning on make a general purpose lab power supply. (3v - 12v, upto 5A). as using normal transformers for the mentioned specifications would make it very heavy i plan on using an unisolated SMPS to initially feed the rest of the circuit in which i am planning to use linear regulators ( LM338) to get the necessary voltages.
my question, is there any problem in using an 'unisolated' supply, isolated supplies are expensive
, thats why deciding to use an unisolated one. pls mention the troubles i could be expecting and is it advicable?
thanks![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
