Overview
The affordable, laboratory grade model BK8502B Programmable DC Electronic Load, from BK Precision, is well suited for testing and evaluating a wide variety of DC power sources. This DC electronic load can operate in CC, CV, CR or CP mode while voltage/current or resistance/power values are measured and displayed in real time and is fully programmable via RS232 or USB interface. Extensive protection, including over temperature, over power, over voltage, over current and reverse polarity will help protect your valuable prototype. Its flexible operating modes and excellent measurement accuracy make this DC electronic load a great choice for characterizing DC Power supplies, DC-DC Converters, batteries, fuel cells and solar cells.
