General description of the
used BK PRECISION 8500
for sale.
The BK Precision 8500 300 W Programmable DC Electronic Load can be used for testing and evaluating a variety of DC power sources. It's wide operating ranges of up to 120 V and 30 A, flexible operating modes and excellent measurement accuracy make the 8500 well suited for characterizing DC Power supplies, DC-DC Converters, batteries, fuel cells and solar cells. The loads can operate in CC, CV, CR or CP mode while voltage/current or resistance/power values are measured and displayed in real time. Load terminals are isolated and floating. Extensive protection, including over temperature, over power, over voltage, over current and reverse polarity will help protect your valuable prototype. The DC loads are easy to use. All parameters can be set quickly and precisely from the front panel, or programmed via RS232 (included) or USB (optional) interfaces. Specifications. Input rating Voltage: 0 to 120 V. Input rating Current: 0 to 30 A. CV Mode Regulation Range: 0.1 to 18 V (Accuracy ±(0.05%+0.02% FS), Resolution 1 mV), 0.1 V to 120 (Accuracy ±(0.05%+0.025% FS), Resolution 10 mV).
