Hi .. i am new in this forum, I hope can find some answers.
I hit a road block to think of away to solve a current issue.
I doing a project call change over supply of 48VDC from 2 different supply. by using a DC coil Contactor.
When this contactor engage with battery power it will instantaneous active and deactive. But when using a rectifier or voltage regulator the are some delay on deactivation process when switch off the power
I know the reason why. Rectifier and the DC voltage regulator discharge the load more slower compare with battery because of the built in capacitor and that's why make the deactivation process have at a second delay..
The issue now, how to can I get instantaneous deactivation by using rectifier and DC voltage regulator?
I try using Resistor to bring down the DC coil voltage but does not help much. I try with additional relay.. is bit faster but is the resuit i need.
I am out of idea. i do hope someone can share some idea.
