The 3ACM_S3 series is a high efficiency green power modules provided by
GAPTEC. The features of this series are: Accept either AC or DC
input, wide input voltage, high efficiency, low power consumption, safety
isolation etc. All models are particularly suitable for the applications such
as industrial, electric power, instrumentation, smart home which do not
have high requirement on EMC.EMC application circuit must be added if
the products need to be applied to EMC harsh environment.

Model selection:
WTC_yyN##
W= Watt; T= Type; C= Case; yy= Vout; N= Numbers of Output;
##= Isolation (kVAC)
Example:
3ACM_05S3
3= 3Watt; AC= AC-DC; M= case style; 5Vout; S= Single Output;
3= 3kVAC
Note:
1. External electrolytic capacitors are required to modules, more details refer to
typical applications;
2. This part is open frame, at least 6.4mm safety distance between the the primary
and secondary external components of the module is needed to meet the safety
requirement;
3. All specifications were measured at Ta=25°C, humidity<75%, nominal input
voltage (115VAC or 230VAC)and rated output load unless otherwise specified;
4. In order to increase the conversion efficiency of the product with light load in the
design, the product will have audio noise when it is operating, but don’t affect
the product‘s reliability and performance;
5. Module required dispensing fixed after assembled;
6. Recommends placing the insulation sheet between the bottom of the curved legs
Module and the PCB board,recommended materials for the FR700, thickness is
more than 0.4mm.
7. All index testing methods in this datasheet are based on our Company’s corporate
standards;
8. We can provide product customization service;
9. Specifications of this product are subject to changes without prior notice.
