Note:

① For models with output voltages of ± 5VDC and ± 9VDC, the maximum output voltage accuracy is ± 5% under 0%-5% load conditions;

② When tested under the working condition of 0% -00% load, the index of load adjustment rate is ± 5%;

③ 0% -5% load ripple & noise is less than or equal to 5% Vo. Ripple and noise test method (twisted pair test method), which can add a capacitive load to the output end to reduce light load ripple.
