DESCRIPTION
The DCHF500W series of DC/DC power converters offers output power of 504W in a 9.84” x 6.30” x
3.43” enclosed case. This series has 2:1 input voltage ranges of 38-60VDC and 72-144VDC and 12V,
24V, and 48VDC single outputs available. Some features include ±10% output adjustability, cooling fan,
and a built-in EMI filter. These supplies are also RoHS compliant. All models are protected against short
circuit, over voltage, over current, and over temperature conditions.
Size: 9.84in x 6.30in x 3.43in
(250mm x 160mm x 87mm)
