SPAC265-8W
AC-DC power supply module
Datasheet − production data
Description
ST's power modules are highly integrated, high
efficiency switch mode converters. The SPAC265
family of converters includes isolated AC-DC,
single output modules. The module can operate in
accordance with the European input voltage
range. It's a turnkey drop-in solution requiring no
additional external circuitry. This specific version
performs 8 W peak output power at 5 Vdc. It can
support 800 mA output current in continuous
mode, and can withstand 1.75 A peak 25% of the
time.

Electromagnetic compatibility SPAC265-8W
6 Electromagnetic compatibility
This section contains specific information about the conformity of the device according to
the Standard IEC 60601-1-2: 2001 + A1:2006.
The SPAC265-8W is a medical device that requires special precautions regarding
electromagnetic compatibility and must be installed and used in accordance with the EMC
information contained in Ta b l e 5 below.
Portable and mobile radio communication, mobile telephones, and pagers can interfere with
the operation of the medical device.
The use of accessories, transducers and cables other than those specified, with the
exception of transducers and cables sold by the manufacturer of the device and the system
as alternatives, can result in an increase of the emissions or in a reduction of the immunity
of the device or system.
Warning: The SPAC265-8W is intended for use in the electromagnetic
environment specified below. The customer or the user of the
SPAC265-8W should assure that it is used in such an
environment
