1ACM_S3 Series
1W- Single Output AC-DC Converter - Universal Input - Isolated & Regulated
AC-DC Converter
1 Watt
Wide input voltage range:
85~264VAC/70~400VDC
Over current protection
Short circuit protection (SCP)
High efficiency, high power
density
Low power consumption,
green power
The 1ACM_S3 series is a high efficiency green power module provided by
GAPTEC. The features of this series are: Accepts either AC or DC input,
wide input voltage, high efficiency, low loss, safety isolation etc.
All models are particularly suitable for the applications such as indust-
rial, 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.
