any circuit
Of course, sir.
Needless to say, it is far more economical to purchase electronic
subsystems to accomplish your task, rather than build from individual
components, much less take the time to actually design a circuit. And
since a busy yet frugal person such as yourself is always pressed for
time (your longest missive to s.e.d. or s.e.b. on this subject being
only twenty-one words in length -- you undoubtedly throw words around
like manhole covers because time is money), I'm assuming you''ll want
to go that route.
For the power supply, the you should purchase a Kepco BOP-36-5
operational power supply, which will provide up to +/-36V at up to 5
amps. You can easily remedy that by connecting an external pot to the
external reference voltages available on the back terminals, then wire
the device up as a non-inverting amplifier, and use feedback resistors
to limit the maximum voltage excursion to +/-24V.
For the display, you may wish to go with an Omega LDP-146-F3-R-1, which
in addition to totalizing, will display voltage in the range requested
in lovely 4" LED numbers. Easy-to-follow instructions for hooking up
the power supply and the display circuit are contained in the
respective equipment manuals.
I hope this has been of service, and this response has provided you
complete satisfaction, as was my exact and specific intent.
Have a nice day
Chris
