Description:
This tester was designed to
allow production like testing in the R&D lab. Quick
setup and ease of use were paramount in the design goals. If
you are interested, the best thing is to just read the
article that was published in the December 1990 issue of
Personal Engineering & Instrumentation News
(click

- 0-72 VDC, 10 amp
programmable power supply (not shown) to drive power
supply under test.
- Four, floating 0 to 5
amp power loads with 1 mA resolution and 0.1%
accuracy.
- DVM is multiplexed to
all four outputs through a solid state, high isolation
multiplexer.
- Very low I/O capacitance
to minimize power supply common mode currents flowing
through the tester.
- Interface to PC is
through a low cost multi I/O card that provides digital
I/O and analog outputs.
- Easy to use, mouse
driven GUI.
- Saves and loads stored
setups.
- Runs universal testing
scripts written in C.
- Very cost
effective.
* The PC / Workbench
name was first published in conjunction with this project in
Personal Engineering, December 1990. It is thus documented
and covered by copyright law.
