1.1 Product Overview
The 8600 Series DC Electronic Loads are versatile instruments used for static and dynamic
testing of DC power supplies, batteries, DC-to-DC converters, and battery chargers. Other
applications include fuel-cell and photovoltaic cell test.
The DC load can be used in one of the following operation modes: constant voltage (CV),
constant current (CC), constant resistance (CR), or constant power (CW). A wide range of
dynamic loading applications can be simulated through user-programmable slew rates, load
levels, duration, and conducting voltage. The DC load can be remotely programmed via the USB,
GPIB, or RS-232 serial interface. Versatile triggering options allow the dynamic load behavior to
be synchronized with other events.
A battery test mode is provided that will measure the ampere-hour (Ah) characteristic of a
battery. Shorts can be simulated by either the front panel or custom programming. The DC
source or other components can be protected from excessive voltage, current, or power, which
will cause the DC load to shut down if excessive levels or reverse polarity are detected.
