Technical data

This reliable series of 500 W dc
power supplies can be controlled
either from the front panel or via an
analog programming voltage. When
used in a test system, the fast up
and down programming helps
decrease test time. Quickly reacting
protection features, including fast
crowbar, CV/CC mode crossover and
over-voltage protection help protect
your valuable assemblies from dam-
age. The linear topology produces
very low ripple and noise, which
allows you to make extremely accu-
rate measurements of the devices
which you are testing.
Lab bench use is enhanced by the
fan speed control, which helps to
minimize the acoustic noise.
