AC-DC Converter

1 Watt

The 1ACOS_S series is a highly efficient green power AC-DC Converter

series. It features wide input voltage range, accepting both DC and AC

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;

2. Unless otherwise specified, parameters in this datasheet were measured under

the conditions of Ta=25°C, humidity<75%, nominal input voltage (115VAC and

230VAC) 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.

5. 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;

7. Products are related to laws and regulations: see „Features“ and „EMC“;

8. Our products shall be classified according to ISO14001 and related environmen-

tal laws and regulations, and shall be handled by qualified units.
