DESCRIPTION
The DCHF350 series of DC/DC power converters offers up to 350W output power in an 8.46 x 4.53 x 1.97 enclosed case.
This series has 12VDC and 24VDC single output models with 2:1 input voltage ranges of 19-36VDC, 36-72VDC, and 72144VDC. Some features include ±10% output adjustability, remote sense (optional), remote ON/OFF control (optional),
and a built-in fan. These supplies are RoHS compliant and are protected against short circuit, over voltage, over load, and
over temperature conditions. All supplies in this series are 100% full load burn-in tested.
