In summary, equipment using DC/DC converters for rail, industrial, and other ruggedized applications in environmentally challenging conditions need to meet special requirements for DC input range, EMC compliance and shock/vibration. When wide temperature swings are also present, these conditions are often coupled with the challenge of condensation. Compliance with fire safety regulations must likewise be addressed. The THN 20WIR series is a quality, off-the-shelf solution that can simplify and de-risk system designing.
