Wide-Range Programmable DC Power Supply AN55(F)

The AN55(F) series is positioned as a new generation of power supplies that combine the advantages of linear and switching types, offering broad applicability. Its internal circuitry employs the latest transformer and power devices, providing pure and stable power while being lighter in weight and offering higher current accuracy. The main circuit topology includes linear voltage regulation, resulting in low current noise and high signal purity. Among them, the standard model features even lower voltage and current ripple and noise, and is equipped with dual current ranges. In the 20mA low-current range, the current accuracy is further enhanced to a current resolution of 1μA. The energy conversion efficiency reaches 75%, which is far superior to ordinary linear power supplies. It is suitable for DC-DC power modules, batteries, motors, semiconductor lasers, automotive electronics, communication electronics, and other devices under test (DUT), applicable in R&D, production lines, metrology institutes, schools, system integration, and other settings. The PV model features high voltage and current transient response, enabling rapid IV curve changes to simulate the IV output characteristics of various solar panels under different environmental conditions (temperature, illumination, shading). This Model features low ripple, low noise, and high-speed MPPT tracking speed. When the MPPT tracking frequency increases, the output accurately conforms to the preset I-V curve. It comes standard with solar matrix simulation software, enabling compliance with photovoltaic standards such as EN50530, Sandia, NB/T32004, CGC/GF004, and CGC/GF035 for solar microinverter I-V curves, specifically covering applications in the solar microinverter and power optimizer testing industry
