Note: 1.The indicated EMC compliance are tighter than EN55024 standard.

2.Ripple and Noise measurement based on the parallel lines test;

3.Unless otherwise specified, all specifications above are measured at rated input voltage and rated output load, Ta=25

°C, humidity < 75%;

4.All specifications stated in this datasheet are subject to the above listed models only. For specifications of non-standard models, please contact our
