The 3ACMW_4 series is a compact size power converter offered by
GAPTEC. It features ultra wide input voltage, taking both DC and AC
input voltage, low power consumption, high efficiency, high re-liability,
safer isolation. Meets UL60950, EN60950, FCC part 15 standards.
Widely used in industrial control and instrumentation, such as electric
power for demanding volume, the requirement of wide input voltage
range, the need to meet UL / CE certification and EMC less demanding
applications EMC application circuit must be added if the products need
to be applied to EMC harsh environment.

1. If the product is not operated within the required load range, the product
performance cannot be guaranteed to comply with all parameters in the datas-
heet;
3. This part is open frame, at least 10mm safety distance between the primary and
secondary external components of the module is needed to meet the safety
requirement;
4. Unless otherwise specified, parameters in this datasheet were measured under
the conditions of Ta = 25°C, humidity <75%, typical application circuit with nomi-
nal input voltage and rated output load;
5. 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;
