Solution needed!!!!…I used a Contactor instead of an ATS to connect 2 power sources (main and ups) for power redundancy

[Raj0089]

I used a Contactor instead of an ATS to connect 2 power sources (main and ups) for power redundancy and the output is connect to a Dell server. i.e, if main power is lost contactor will changeover to ups power and there should be continuous power supply for the dell server…

but i have a problem!!!

.during changeover my Dell server turn off (restarting). I think this is due the switching/changeover delay of the contactor…can someone help and propose the best solution..

Why aren't you feeding power to the Ups and the ups to the server?
