I'm a DC guy but I think my calculations could work in AC too. I just need confirmation before start putting things together
Ok, I have a 3D printer it draws 5amps, 220 volts its internal power supply can't hold up for 10ms ( average relay operation time )
So I'm thinking about using AC power.
based on my calculation:
Energy = Power x time ( in sec)
Power = Voltage x current
so my total Jouls in second is
5x220x1 = 226 j/s ok I need to feed 226 jouls for 1 second to keep my printer active for relay to switch
now, to be on the safe side I want double my uptime.
I believe a 50uf is more than enough Am I right?
I wan't to put the capcitor in paraller with the printer and the power source
