Product specifications

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.
High Performance DC Power Supplies speed and accuracy for test optimization
