Subject: Load Testing PDP11 Power Supplies
I am making progress testing the power supply for my 11/04 (BA11-K
chassis) and so far have worked through the power control box,
transformer,
fans and the 15VDC regulator/Power Line monitor but
have one question for
the group....
I am seeing in tolerance output voltages from the 15VDC regulator but I
haven't loaded tested it. Is this something I should do or if the
unloaded
outputs are within tolerance then it is safe to use
(once the other
regulators
are done)?
No real technical info but a description of progress so far on
http://www.quicktrip.co.nz/jaqblog for those interested in a few pictures.
I am about the start on the H744 5VDC regulators.
Regards
Andrew
The suggestion I have had is to use 12V car/motorcycle bulbs to provide some
load.
