* This series of products using reduced frequency technology, the switching
frequency is test value of full load. When the load is reduced to below 50%,
the switching frequency decreases with decreasing load.

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 The maximum capacitive
load offered were tested at nominal input voltage and full load;
2. Unless otherwise specified, parameters in this datasheet were measured under
the conditions of Ta = 25°C, humidity <75%RH with nominal input voltage and
rated output load;
3. All index testing methods in this datasheet are based on our Company’s
corporate standards;
4. The performance parameters of the product models listed in this manual are
as above, but some parameters of non-standard model products may exceed
the requirements mentioned above. Please contact our technicians directly
for specific information;
5. We can provide product customization service;
6. Specifications are subject to change without prior notice.
