SSL20C Series

Single Output External P o wer Supply

The SSL20C series is a 20W universal input AC/DC external Class II power supply in a

4.65 x 2.40 x 1.08 inch plastic enclosure. The SSL20C represents the next generation of

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

power applications. The SSL20C provides up to 20W under natural convection cooling.

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

and meets EN55022 level B for conducted emissions. The SSL20C has several output

voltages available ranging from 5V to 48V. 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
