The SSL40 series is a 40 W universal input ac-dc external power supply in a 4.21 x 1.77 x
0.98 inch plastic enclosure. The SSL40 is a low cost series with six single output models in a
very small package providing a pre-approved external power solution for a host of
worldwide low power portable and desktop applications. The SSL40 provides 40 W of output
power with free air convection cooling. Standard features include universal input,
overvoltage, short circuit protection and EN55022 conducted emissions level B. The series,
with full international safety approval and the CE mark, provides pre-approved SELV outputs
without the need for further safety approval or mechanical integration into the application
system. The SSL40 series is designed for use in low power, portable and desktop data
networking, computer and industrial applications requiring low cost external power adapters
in a small package.
