AUTO MODE

The 4200 contains a unique Auto Mode that pro-
vides glitchless automatic switching between CR,
CC, CV and CP limits. Previously challenging tests
that are now made possible include turn-on into a
CR load, confirming the complete V-I curve for
lithium-Ion battery chargers, and preventing device-
under-test blowup should a protection circuit fail.

POWERFUL TRANSIENT GENERATOR

A greatly expanded range of single burst or continu-
ous waveforms are now possible through the built-in
waveform/transient generator. Almost any waveform
can be created with up to100 programmable steps.
Waveforms can be programmed in the CV, CP and
CR modes as well as the customary CC mode.

COMPATIBLE WITH THE HIGHLY FLEXIBLE POWER
MODULE SUBSYSTEM

Within the mainframe power module chassis, the
Model 4200 may be combined with Model
4100/4110 loads as well as 6000/6100 Series DC
sources. The 4200 is also software parallelable,
which allows real time reconfiguration of larger, vir-
tual loads. In this manner, the load creates another
dimension of power module flexibility that assures
adapting to new numbers of outputs and power level
needs in the future.
