COMPLEX LOAD PROFILE PLAYBACK
To facilitate ease of re-creating complex, precisely
timed, multi-mode load profiles, a 100-step macro-
recording capability allows capturing a dynamic
sequence for later playback from within the Load.
Additional complex profiles can be stored in a system
controller library to be downloaded to the Load when
required.
FAULT TOLERANT
The 4700 Loads are designed to keep running under
just about any condition, even certain internal
component failures. Standard for this class of
instrument is protection against output over-voltage,
over-current, over-power, reverse-voltage, and internal
over-temperature. In addition, controller intelligence
continuously monitors sub-circuit performance and
redistributes the current load as necessary. This fault
tolerant technique allows the user to continue testing
with proper warning of a fault condition. Further load
reliability is assured through extensive startup self-test
and real-time monitoring.
FIELD EXPANDABLE
Because the 4700 Loads are modular, synchronously
controlled and actively power-balanced, they operate
efficiently in parallel as a single load. In this manner the
Loads are field expandable with changes only to the
input connections. This feature allows selection of only
what is currently needed with confidence that future
higher power requirements can be accommodated with
minimum disruption and cost.
