Powering Communications and Technology 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.
