Note:
1. Recommend to use module with more than 5% load, if not, the ripple of the
product may exceeds the specification, but does not affect the reliability of the
product;
3. The recommended unbalance degree of the dual output module load is ≤ 5%;
if the degree exceeds 5%, than the product performance cannot be gua-
ranteed to comply with all parameters in the datasheet. Please contact our
technicians directly for specific information;
4. The maximum capacitive load offered were tested at nominal input voltage and
full load;
