Notes:

Note8:

MTBF is referring RAC04-3.3SC/277

Notes:

Note5:

An external input fuse is recommended: T1A slow blow type

Note6:

To measure the output ripple and noise short runs by 0.1µF/50V & 47µF/50V @20MHz, nominal input and full load.

Note7:

An external MOV is required for 230VAC operation. (MOV model: shall comply with IEC 61051-2, e.g. Epcos S14 Series.
