A switch for 2 power source for a single amp

abcbeck · 7th August 2011, 05:52 AM

I have a requirement as backup psu for an amp

so I need to switch PSU A to PSU B , instantly with a switch or by relay

just want to know will the amp suffer and loss of power, when the instant is being switch from A to B?

or should I have a cap reservoir after the switch to buy some time for to switching

How do PSU A and PSU B outputs differ?

I think it should work too, probably will find a fast relay switch
