[sci.electronics] Wntd: Schem. for DEC H7100A pwr sply

pda@rsiatl.UUCP (Paul D. Anderson) (07/16/90)

I have obtained 2 Digital H7100A power supplies (100A @ 5v) that I am
planning on using to build a UPS.  One of the steps involves raising
the switching supply to provide about 6.5 volts.

After going over the hardware for some hours, I have been unable to 
ascertain where the overvoltage circuit is located, although I have been
able to get the voltage up to 5.8 volts- almost there, but not quite
enough.

Does anyone have a schematic on this supply that they could coach me
with or would be willing to part with (or perhaps a photocopy).  
Or maybe you have done this and might could tell me a trick about 
the hardware.  If you could, please email me.  I'd sure appreciate it.  

Thanks,
-paul
