Technical data

This series of 2000 watt dc power
supplies has the exceptional, proven
reliability that test system engineers
look for. 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
be 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 extreme-
ly accurate current and voltage
measurements.
