The SSL20C series is a 20 W 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 20 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 SSL20C has several output
voltages available ranging from 5 V to 48 V. The series has full international safety
approvals and carries the CE mark to provide pre-approved SELV outputs.
