how we can recognize from each other?as i know isolate will don by TR primary and secondary separation winding ?why non isolate save 30 power with same power factor ????

 

i need help why no comment ?????

 

If you mean, why use isolated psus instead of non-isolated ones, because isolated types are safer to use, they can control the current, whereas non-isolated is cheaper to produce and doesn't create wasted heat.

You mean by control current =when voltage vary current vary to give same power .....i which type create wast heat ??and in which part of driver ??

Dave is right. A non-isolated power supply connects one side of the supply line to the output. Having one side of the line connected to something provide s a chance for getting serious shocks and for starting fires, and, in addition, for damaging ht device being powered. Also, there are quite a few other reasons for using an isolated power supply.
