In summary: The B&K Precision 8500B Series is a family of value-tier programmable DC electronic loads delivering 150 W to 1500 W of sink capability across voltage ratings of 120 V, 150 V, and 500 V. All models share the same CC, CV, CR, and CW operating modes; list-mode and battery test functions; CR-LED mode for LED driver simulation; and full protection coverage including LRV/RRV reverse-voltage protection.
The 8500B Series is used for testing DC power supplies, DC-DC converters, batteries, battery chargers, photovoltaic solar panels, and LED drivers. The CR-LED mode lets engineers simulate the loading behavior of an LED string without wiring physical LEDs. Built-in battery test mode supports discharge profiling with stop conditions and capacity reporting in ampere-hours.
Engineers select 8500B when they need a programmable, multi-mode DC load at a benchtop price point. The 8514B at 1500 W in a 2U half-rack form factor is one of the highest power densities at this price tier, while the 8502B covers 500 V applications such as photovoltaic panel I-V curve verification.
8500B Series models deliver CC-mode accuracy of ±(0.05% + 0.05% F.S.), transient mode up to 10 kHz, adjustable slew rate, and a full feature set including list mode, automatic test mode, and battery test. Standard interface is a DB9 (TTL) with USB adapter on the legacy models; the 8514B adds direct USB (VCOM) and RS232.
The 8500B Series is the value-tier reference in the professional DC electronic load market — recommended in industry training as the entry point for power-supply test, LED-driver test, and small-format battery characterization at a fraction of the cost of full performance instruments.
The 8514B is the 1500 W member of the 8500B Series in a 2U half-rack chassis, delivering up to 120 V and up to 240 A of sink current. CC-mode accuracy is ±(0.05 + 0.05% FS) across both low and high current ranges, with a minimum operating voltage of 2.5 V at full scale. The 8500B platform supports list mode, automatic test mode, battery test mode, and CR-LED mode (for LED-driver loading simulation), and includes OVP, OCP, OPP, OTP, and both local and remote reverse-voltage protection.
