General Information
1.1 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.
Features:
• CC/CV/CR/CW operating modes
• List mode
• Transient mode
• Measurement speed up to 40 kHz
• Remote sense function
• Battery test function
• OCP and OPP automatic test
• CR-LED function
• Store/recall up to 100 setups
• Analog current monitoring
• Adjustable slew rate in CC mode
• OVP/OCP/OPP/OTP and reverse voltage protection
1.2 Package Contents
Please inspect the instrument mechanically and electrically upon receiving it. Unpack all items from the shipping carton,
and check for any obvious signs of physical damage that may have occurred during transportation. Report any damage
to the shipping agent immediately. Save the original packing carton for possible future reshipment. Every instrument is
shipped with the following contents:
• 8500B series DC Electronic load
• IT-E132B USB to TTL adapter
• AC Power Cord
