The 8500B Series programmable DC electronic loads improve upon all aspects of its predecessor while maintaining dependability at a value price. A set of comprehensive functions make these loads a versatile tool for testing and evaluating DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays.

List mode, transient mode, automatic test mode, and battery test mode offer a variety of test tools for lab or production line applications. Continuously switching and pulsing load conditions put a dynamically changing load on DC sources. Load behavior can be triggered internally, externally, or remotely from the included application software.

Contained in a compact benchtop form factor, these loads operate in constant current (CC), constant voltage (CV), constant resistance (CR), or constant power (CW) mode. Internal memory allows for 100 sets of user configurable parameters such as voltage, current, slew rate and width for quick system recall.

Remote control and programming

Built-in rise and fall time measurement

The 8500B Series can measure the rise or fall time from a specified start and stop voltage level of the measured input without the need for an oscilloscope. This function can also be used as an internal timer to count how long the input has been enabled.

Application software

PC software is provided for front panel emulation, generating and executing test sequences, or logging measurement data without the need to write source code. Additionally, this application software integrates with NI Data Dashboard for LabVIEW applications, allowing users to create a custom dashboard on a tablet computer or smart phone to remotely monitor 8500B Series DC loads.

• Remote monitoring on iOS, Android or Windows 8 compatible tablets or smartphones
• Log voltage, current, and power values with timestamp
• Run transient operation and list mode programs remotely
• Create an unlimited number of external list files to be executed from PC memory

SCPI and Legacy Protocol

The 8500B series supports the SCPI protocol which is the industry standard for remote communication. The 8500B series also maintains backward compatibility for system integrators still using the legacy 8500 series proprietary (26 byte) protocol.
