BK Precision 8612B-220V 500V, 30A, 750W Programmable DC Electronic Load, USB and RS-232 Interfaces, 220V Line Input. The 8612B programmable DC electronic load provides the performance of modular system DC electronic loads in a compact benchtop form factor. With fast transient operation speeds up to 25 kHz, and high 16-bit measurement resolution and accuracy, these DC loads can be used for testing and evaluating a variety of DC sources such as DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. The DC electronic loads can operate in constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW) mode. The instrument provides flexible triggering capabilities, analog current control and monitoring, and standard USB (USBTMC-compliant) or RS-232 serial interfaces for remote communication. The 8612B also has an input power of 750 Watts and a maximum input voltage of 500 Volts.
