The 2ACA_3 series is the compact size power converters series offered
by Gaptec. It features compact size and 3000VAC safer isolation. It of-
fers good EMC performance, meets IEC61000, UL60950 and IEC60950
standards, and is widely used in industrial, electricity, instruments and
civil applications.
If it is planned to be used in electricity and other higher requirement to
EMC applications, one must connect a typical application.
