OES SERIES
40 WATT
DESCRIPTION
OES DC/DC converters are ultra-dense, 40
Watt, single output converters produced for the
telecom and networking markets. Making use of
open-frame packaging, planar magnetics, high
efficiency topologies, and surface-mount design,
the OES has superior thermal performance.
The OES features 1500 VDC isolation and
overvoltage protection, as well as input
undervoltage lockout.
