Specifications

This 2000 W DC power supply
provides over 2000 watts at either
70 or 80 volts. This makes it par-
ticularly 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 imme-
diate 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 mea-
surements.

DC floating voltage: Output terminals can
be floated up to ±240 VDC maximum from
chassis ground.
Remote sensing: Up to half the rated
output voltage can be dropped in each
load lead. The drop in the load leads
subtracts from the voltage available for
the load.
