SSL40C Series

Single Output External P o wer Supply

The SSL40C series is a 40 W universal input ac-dc external Class II power supply in a

4.65 x 2.40 x 1.08 inch plastic enclosure. The SSL40C represents the next generation of

low cost external power supplies, suitable for a host of worldwide low power external

power applications. The SSL40C provides up to 40 W under natural convection cooling.

Standard features include universal ac input, overvoltage and short circuit protection

and meets EN55022 level B for conducted emissions. The SSL40C has several output

voltages available ranging from 12 V to 48 V. The series has full international safety

approvals and carries the CE mark to provide pre-approved SELV outputs.

All specifications are typical at nominal input, full load at 25 °C unless otherwise stated
