SPAC265-3W
AC-DC switch mode power supply
Encapsulated
Description
ST's power modules are highly integrated, high
efficiency switch mode converters.
The SPAC265-3W isolated series delivers 3 W at
12 V from universal AC input. It is an immediate
drop-in solution requiring no additional external
circuitry.
The power supply modules are fully encapsulated
offline board-mount devices suited for main and
auxiliary power requirements in appliance,
industrial and communication application.
The open frame version is intended to offer a
low-cost version of ST's easy to use, compact
size power modules.
