Programmable DC Electronic Loads

1 Programmable DC Electronic Loads8600 SeriesData data subject to change B&K Precision Corp. 2015 The 8600 Series Programmable DC electronicloads provide the performance of modular systemDC Electronic Loads in a compact benchtop formfactor. With fast transient operation speeds andhigh 16-bit measurement resolution, these standalone DC Loads can be used for testing andevaluating a variety of DC sources such as DCpower supplies, DC-DC converters, batteries,battery chargers, and photovoltaic DC Loads can operate in constant current(CC), constant voltage (CV), constant resistance(CR), or constant power (CW)

4 All load parameterssuch as voltage, current, slew rate, and widthcan be set via the front panel or programmedremotely. The 8600 Series provides standardUSB (USBTMC-compliant), GPIB, or RS-232serial interfaces for remote communication. To ensure the reliability of your testing, the 8600 Series provides a power-on system self-test andnumerous protection features: overtemperature(OTP), overvoltage (OVP), overcurrent (OCP),overpower (OPP), and local/remote reverse voltage (LRV/RRV) ApplicationsThe 8600 Series provides a built-in battery testmode to measure the ampere-hour (Ah)

7 Up to 100different sequences can be linked to run steps ofvarious operating modes and loading sequence can also be programmed withupper and lower limit Pass/Fail criteria. Whenapplied in production testing, you can easilyjudge whether the test parameters of yourdevices are within the specification limits andadjust your process according to the modeNot limited to just switching between two levels,list mode lets you generate more complexsequences of input changes with several differentlevels. Up to 7 groups of list files can be savedand executed in CC mode via internal or externaltrigger.
