The 1ACM_S3 series is a high eciency green power module provided by
GAPTEC. The features of this series are: Accepts either AC or DC input,
wide input voltage, high eciency, low loss, 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.

Example:

1ACM_05S3
1 = 1Watt; AC = AC-DC; M = case style; 5Vout; S = Single Output;
3 = 3kVAC

Note:

1. Models listed with strike-through text have been ocially discontinued.

2. Unless otherwise specied, all specications are measured at rated input voltage
and rated output load, TA=25°C, humidity < 75%.

3. All specications stated in this datasheet are subject to the above listed models
only. For specications of non-standard models, please contact our technical

Note:
C1, C2 and C3 are electrolytic capacitors. They are required both AC input and DC
input.
The value of C1 is recommended to be 4.7µF /400V. When the input voltage is above
370VDC, the recommended value of C1 is 4.7µF/450V). C2 and C3 are output ler
capacitors, they are recommended to be high frequency and low impedance elec­trolytic capacitors. Capacitance and rated ripple current of capacitors refer to the
datasheets provided by the manufactures. Voltage derating of capacitors should be
80% or above. C4 is a ceramic capacitor, which is used to lter high frequency noise.
C2, C3 and L1 form a pi-type lter circuit. Current of L1 and L2 refer to the datasheets
provided by the manufactures, current derating should be 80% or above. TVS is a
recommended component to protect post-circuits (if converter fails).
