HEC50-S 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 silicon. All models feature a wide
input range, trimmable output voltage and a 15A current rating. Remote sense and
remote on/off facilities are included as standard, and the converters are
comprehensively protected against over-current, over-voltage and over-temperature
conditions. The HEC50 converters are especially suited to telecom, networking and
industrial application.
