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 30cm long, 1mm² cross-section parallel stranded wire 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 100Hz 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: When the load is at the rated value, the input voltage varies within the rated range; Lo load regulation: When the input is at the rated voltage value, the load varies from zero to the rated value.
