Specifications

This series of linear-regulated
80-100 W DC power supplies is
designed to maximize the throughput
of DUTs through the manufacturing
testprocess.Bothprogramming
and measurement are optimized for
speed. The active downprogrammer
can sink up to the full rated current
of the power supply, which quickly
brings the power supply output to
zerovolts.The6630Bseriesoffers
many advanced programmable
features including stored states
and status reporting. Programming
is done using industry standard
SCPIcommandsviatheGPIBor
RS-232. Test system integration is
further simplified by using the
VXIPlug&Play drivers. The optional
relays simplify system design and
troubleshooting.
The optional front panel binding
postsmakethe6630Bseries
convenient on the R&D lab bench.
The built-in microamp measurement
system helps the engineer to easily
and accurately monitor the output
voltage and current without a
complicated test setup.
