Product application

The ANGS series Programmable AC est power supply can simulate overvoltage/undervoltage, over-frequency/under-frequency, low (zero) voltage ride through and other curves. The overvoltage/undervoltage, over-frequency/under-frequency, anti-islanding protection of inverter can be tested with anti-islanding load or AC electronic load. AN53s series solar cell simulator can simulate a variety of I-V curves of solar cell to verify the inverter's maximum power tracking capability, and conduct inverter aging test and overvoltage/undervoltage protection; AN87600(F) multi-channel power analyzer can analyze the inverter’s power, harmonics, efficiency and other parameters, so as to conduct comprehensive analysis of inverter performance. Three kinds of equipment can be integrated using professional PC test software to form a comprehensive inverter test system and solutions.
