One of the six power supplies supplying the Amdahl CPU with DC electricity.
It weighs 49.6Kg. I have not opened it to look inside
but it must contain a beefy transformer.
The output was from thick cables bolted
to the two big lugs on the top.

One of the six power supplies supplying

It weighs 49.6Kg. I have not opened it to look inside
but it must contain a beefy transformer.

End view, the CAUTION

is not overstated.
The input was 208VAC at 12AMPS, 400Hz.
It came from a Rotary Convertor
which was a large 3 phase electric motor
powered by mains electricity, 240V 50Hz 3 phase
that turned an axle on which was mounted a
generator creating the 3 phase 400Hz supply.
This arrangement filtered out all blips and glitches
in the mains supply to the Rotary Convertor.
It could even provide power through a sub-second
blackout by the rotary inertia of the machine.
The output was 5.2/3.6/2v DC at 420AMP.
It must have been just one of these voltages
because there is only one output.
