[RFI] OT Curiosity - Bel HB5-3/OVP-AB

[Michael Carter]

If you find out what its purpose in life once was,
I would like to know.  I acquired a box full of
similar supplies, mostly made by PowerOne.
They have relatively high amperage +5V DC outputs,
and typically +/- 12 or +/- 15 V at less than 1 A
each as separate outputs.  My guess is that they
were intended for powering TTL logic boards with
some analog functions (op amps) needing the
dual polarity supplies.

I got this supply as part of a purchase of a couple of SDRs.  It's
linear, input voltages of 100-240 volts, 5 volts at 3 Amps out, and has
a very elaborate rectifier/regulator board with a specialized regulator
IC.  In some respects it is tempting to keep around to power 5-volt
devices, but its physical packaging is awkward.  The transformer and
circuit board are mounted on an L-shaped piece of thick aluminum, which
has 8 large holes that seem intended for some sort of standard
mounting.  It is still for sale on the manufacturer's web site.

More to satisfy my curiosity than anything else, does anyone know what
it's intended for.
