DC power supplies have solar array simulation function
B&K Precision's PVS series of 5100 W dc power supplies offer 1000 V and 600 V models with built-in solar array simulator function.
B&K Precision's PVS Series of programmable dc power supplies are designed to deliver output power up to 5.1 kW while providing strong regulation, low noise, and fast transient response times. All models provide a built-in solar array simulator (SAS) function to generate photovoltaic I-V curves. These dc power supplies are suitable for high voltage testing up to 1000 V, motor inverter testing, and solar array testing applications. PVS Series users can simulate solar arrays under different weather conditions during a day to validate the effectiveness of the solar inverter. The SAS software allows for I-V curve input parameters (Voc/Isc/Vmp/Imp/FF/FFv/FFi) along with user-definable irradiance profiles, and a custom 1024-point voltage and current table. For programming, the power supplies provide a list mode function, an external analog programming and monitoring interface, and standard USB, RS-232, GPIB, and LAN interfaces supporting SCPI commands.
