Battery Operation of MP

Not long ago we had a series of messages on the MP reflector about battery operation. One of my suggestions was to put a battery on the output of the power supply to maintain continuous operation during power outages and
emergency operations. Turns out that the Astron power supply company had that idea in mind and they provided circuit details on how to do that with their power supplies.
 

The jpeg images for the circuit data comes to about 2.77 megabytes. You can download them here:
