Data Sheet Programmable DC Electronic Loads 8600/B Series The 8600/B Series programmable DC electronic loads provide the performance of modular system DC electronic loads in a compact benchtop form factor. With fast transient operation speeds and high 16-bit measurement resolution, these standalone DC loads can be used for testing and evaluating a variety of DC sources such as DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. The DC loads can operate in constant current (CC), constant voltage (CV), constant resistance (CR), or constant power (CW) mode and be configured to provide a dynamically changing load to the DC source with fast load switching times. Versatile internal, external, and remote triggering options allow the dynamic load behavior to be synchronized with other events. Increase productivity by saving your test parameters into any one of the 100 memory areas for quick system recall. All load parameters such as voltage, current, slew rate, and width can be set via the front panel or programmed remotely. The 8600/B Series provides standard USB (USBTMC-compliant) and RS232 interfaces standard for remote communication. GPIB is available as an option on select models. To ensure the reliability of your testing, the 8600/B Series provides a power-on system self-test and numerous protection features: overtemperature (OTP), overvoltage (OVP), overcurrent (OCP), overpower (OPP), and local/ remote reverse voltage (LRV/RRV) protection.

Programmable DC Electronic Loads 8600/B Series Flexible operation Transient operation List mode Automatic test mode Transient operation enables the module to periodically switch between two load levels. A power supply's regulation and transient characteristic can be evaluated by monitoring the supply's output voltage under varying combinations of load levels, frequency, duty cycle, and slew rate. Transient operation can simulate these conditions. List mode lets you generate more complex sequences of input changes with several different levels. Up to 7 groups of list files can be saved. Each...
