input voltage, high efficiency and low power consumption. The pro-
ducts are widely used in industrial control instrumentation, electric po-
wer applications and smart home type applications, the need to meet
UL/CE safety certifications and lower demand for EMC compliance le-
vels. For extremely harsh EMC environment, we recommend using the
application circuit show of this datasheet.

Note:
1. External electrolytic capacitors are required to modules, more details refer to
typical applications;
* Ripple and Noise are measured by the method of parallel lines.
2. Unless otherwise specified, parameters in this datasheet were measured under
the conditions of Ta=2ꢀ°C, humidity<ꢃꢀ5, nominal input voltage ꢁ11ꢀVAC and
230VACꢂ and rated output load;
3. In order to improve the efficiency at light load, there will be audible noise gene-
rated, but it does not affect product performance and reliability.
4. The module needs to be glued and fixed after assembly.
ꢀ. All index testing methods in this datasheet are based on our company corporate
standards;
6. We can provide product customization service, please contact our technicians
directly for specific information;
Example:
3ACOS_12S
3= 3Watt; AC= AC-DC; A= case style; 12= 12Vout; S= single output
ꢃ. Products are related to laws and regulations: see „Features“ and „EMC“;
+. Our products shall be classified according to ISO14001 and related environmen-
tal laws and regulations, and shall be handled by qualified units.
