Specifications

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.
