Technical data

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.

of the output current rating of the supply.
