APPLICATION
4700 LXI Series Electronic Loads are designed for testing applications that require high-power and high-current
plus measurement of UUT dynamic performance. The Loads provide exceptional reliability combined with the
inherent simplicity and safety of air cooling. The 4700 Loads are controlled through either a manual touch-panel, a
LabVIEW soft-panel or an emPower™ Test Executive enabled automatic test station. Typical power conversion
products to be tested include higher-power DC supplies, telecom rectifiers, fuel cells and batteries.

EXTENDED INTERNAL MEASUREMENTS
The 4700 Loads eliminate the need for separate external
instruments and related switching to capture timing and other
dynamic measurements during UUT turn-on and turn-off. This
is accomplished by incorporating the task-essential features of
a DMM, DSO and Transient Generator. With this built-in
capability, the 4700 can rapidly generate engineering-
characterization-like test information at faster test speeds with
the additional benefit of cost savings from fewer measurement
instruments, switches and interconnection wiring.

AUTO MODE
The 4700 contains a unique Auto Mode that provides
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.
