OET SERIES - TRIPLE OUTPUT, 25 WATT
DESCRIPTION
OET triple output DC/DC converters provide 25 watts
of output power in an industry-standard package. The
OET series features excellent efficiency and industry-
leading power density. The OET features open-frame
packaging to provide maximum useable power with
minimal thermal constraints. These units are fully
compatible with production board washing processes.
