DESCRIPTION
OES SERIES
40 WATT
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.

Notes
† MTBF predictions may vary slightly from model to model.
Specifications typically at 25°C, normal line, and full load, unless otherwise
stated.
Soldering Conditions: I/O pins, 260°C, ten seconds; fully compatible with
commercial wave-soldering equipment.
Units are water-washable and fully compatible with commercial spray or
immersion post wave-solder washing equipment.
