General Information
3.1 Product Overview
The 8500B Series DC Electronic Loads are versatile instruments used for static and dynamic testing of
DC power supplies, batteries, DC-to-DC converters, battery chargers, and other applications including
fuel-cell, and solar cell test. Primary modes include constant voltage (CV), constant current (CC),
constant resistance (CR), and constant power (CW). A wide range of dynamic loading applications can
also be simulated through user-programmable slew rates, load levels, duration, and conducting voltage.
Further, transient, list mode, battery mode, and LED modes further extend testing capabilities. Versatile
triggering options allow the dynamic load behavior to be synchronized with other events. The DC load is
remotely programmable via the TTL serial interface. This interface requires 0-5V signal levels and can
connect to typical serial ports via an adapter such as the IT-E132B.
