Note: 1) All the above test indicators were measured under the following conditions: within the rated input voltage and rated output load range, the environment was 25℃, 85%RH, and there was no wind.

2) Output DC voltage ripple test: A parallel stranded wire with a length of 30cm and a cross-section of 1mm², with 0.1μF and 0.47μF capacitors connected to one end, was bypassed at the test point. The maximum peak-to-peak value of the main frequency ripple Vp-p100Hz and the maximum peak-to-peak value of the combined ripple Vp-pmax were measured respectively.

3) Li voltage regulation rate: When the load is at the rated value, the input voltage varies within the rated range; Lo load regulation rate: When the input is at the rated voltage value, the load varies from zero to the rated value.
