B&K Precision’s 8500B Series DC electronic loads with up to 0.1mV / 0.1mA of resolution

Backward compatible with the legacy 8500 series protocol as well as offering support for industry-standard SCPI commands, B&K Precision’s 8500B series of programmable DC loads is suitable for testing DC-DC converters, batteries, battery chargers, and photovoltaic arrays.

The programmable DC electronic loads support constant current, constant voltage, constant resistance, and constant power operation, with list mode, transient operation, automatic test mode, battery test function and an adjustable slew rate. Transient mode in CC mode is up to 10kHz. The 16-bit voltage and current measurement system provides up to 0.1mV / 0.1mA of resolution with flexible triggering options including from the front panel, an external input, a timer, or a bus. The loads also include PC software for front panel emulation and generating test sequences and are compatible with B&K Precision’s battery test software for discharge tests. The 8500B series consists of four models each in a 2U (half-rack) form factor.
