Description:
Most OEM's realize the value
of being able to test at the subsystem level, but most don't
realize just how cheaply and fast a small dedicated power
supply tester can be built - so they don't even try. In the
critical start-up phase of any major project launch, when
all the various parts are coming together for the first
time, it's very critical to be able to monitor the quality
of complex subsystems. This is especially important when
little experience exists for new suppliers. In my experience
many give quality little thought and they must be monitored
from the start until a solid record of performance is
established.
A small system like this
that uses a cheap (or even scrap) PC as a controller, a
leveraged data acquisition controller - like my PIC DAS, a
programmable input source and Multimeter. The relay
multiplexer and electronic, constant current load bank are
built breadboard style, throw in a test program written in
VEE and Viola! A complete turn-key test system built in a
day or two. Try to beat that for cost effectiveness!
- PIC DAS based control
for fast / leveraged design.
- 60 watt, Six output test
station.
- Plug in test head for
manufacturing line flexibility and use by many supply
designs.
- Uses what is hard to
build, but easy to buy - Programmable input source,
DVM
- Leverages what is
expensive to buy but easy to build - DVM Switching Matrix
and constant current loads.
- VEE test program using
highly leveraged routines.
- Quick - Accurate - Cost
effective test!
