Note: 1) The above detection indicators are measured under the following conditions: within the input rated voltage and output rated load range, the environment is 25℃, 85%RH. , when there is no wind around 2) Output DC voltage ripple detection: Use a parallel twisted wire with a length of 30cm and a cross-section of 1mm2 connected to one end of a 0.1μF and 0.47μF capacitor to bypass the detection point and detect 100Hz respectively. The maximum peak-to-peak value of the main frequency ripple is Vp-p100Hz and the maximum peak-to-peak value of the comprehensive ripple is Vp-pmax. 3) Li voltage regulation rate: when the load is at the rated value, the input voltage changes within the rated range; Lo load regulation rate: when the input is at the rated voltage value, the load changes from zero to the rated value. |
