3ACM_S3 Series
3W- Single Output AC-DC Converter - Universal Input - Isolated & Regulated
AC-DC Converter
3 Watt
Ultra wide input voltage:
85~264VAC/70~400VDC
Over current protection
Short circuit protection (SCP)
High efficiency, high power
density
Industrial grade
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.
Open frame, ultra small size
Flexible design of peripheral
circuit reduces layout
problems
Meets IEC60950/EN60950/
UL60950

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;
