DESCRIPTION
HEC50 single output DC/DC converters provide up to 50 watts of output power in
an industry standard half-brick package and footprint. These units are specifically
designed to meet the power needs of low-voltage silicone. All models feature a
wide input range, adjustable output voltage and a 15A current rating.
