DC – Power Supply and the Specs are below
· Input : – 230 V (AC) @ 50 Hz (India) and 240 V (AC) @ 60 Hz (USA)
· Output : – 24 V (DC) , 6 Amps
· Input spike / line filter
· Short circuit protection (resettable)
· Over load protection (resettable)
· Easy to access interchangeable fuse with spare fuse holder
· LED Indicators for I/P , O/P and Faults
· Fan cooled (if required since this entire system including various other electronics instruments will inside a 1m x 1m x 1m completely covered cabinet )
· The PSU can be LINEAR or SMPS type ( which ever can be delivered faster )
Hello Ramu,
On prima facie, as the current requirement is high with high DC output, it would be good to have two power supplies internally.
You may use LM723C for voltage regulation.
It’s a linear regulator and you may need heat sink.
Use an auxilliary power supply (derived from the main AC in) for powering up LM723C.
Faults can be detected using simple high input impedence comparator circuits.
