Product Introduction                          

XL-831 Single-phase Programmable Standard Power Source Features excellent output performance, capable of accurately outputting AC current from 0 to 120A and AC voltage from 0 to 420V, with a frequency adjustment range of 40Hz to 65Hz. This device can generate extremely pure sine voltage and current signals with very low distortion, not exceeding 0.1%, typically only 0.03%, fully meeting high-precision testing requirements. Mainly used in scenarios requiring precise and certain power AC voltage and current, generally for AC calibration and inspection. Suitable for power departments, metrology departments, quality inspection departments, research institutions, universities, and production and R&D enterprises related to electric meters, distribution terminals, power management, load control, power quality, reactive power compensation, etc.
