• UL, CSA and VDE safety approvals

• Available RoHS compliant

The SCL25 series is a 25W universal input AC/DC external power supply in a 6.32 x

3.35 x 1.5 inch plastic enclosure. The SCL25 series has a single output and dual

output model in a low profile package providing a pre-approved external power

solution for a host of worldwide low power portable and desktop applications. The

SCL25 provides 25W of output power with free air convection cooling which can peak

at 30W for 60 seconds. Standard features include universal input, 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 SCL25 series is designed for use in low power, and desktop

data networking, computer and industrial applications requiring external power

adapters in a low profile package.
