Technical data

This 2000 W dc power supply
provides over 2000 watts at either
70 or 80 volts. This makes it partic-
ularly suitable for a variety of test
scenarios for 48 volt systems.
Telephone network equipment is
one example of such a 48 volt bus
application. It also has the unusual
combination of high efficiency and
low noise operation.
Programming of the dc output and
the extensive protection features
can be done either from the front
panel or using industry standard
SCPI commands, via the GPIB.
Using the serial link, up to 16
power supplies can be connected
through one GPIB address.
Test system integration can be
further simplified by using the
VXIPlug&Play drivers. The output
voltage and current can also be
controlled with analog signals. This
is helpful for certain types of noisy
environments, and also immediate
reactions to process changes.
Lab-bench use is enhanced by the
fan-speed control, which minimizes
acoustic noise. The extremely low
ripple and noise helps the built-in
measurement system make
extremely accurate current
and voltage measurements.
