The RP08-AW series wide range input DC/DC converters are certified to UL 60950-1 and cUL 60950-1.
This makes them ideal for all telecom and industrial applications where approved safety standards are
required. The 24V and 110VDC input versions have been especially designed for railway applications.
The DIP24 package is available in both pinned and SMD case styles and meets military standards for
thermal shock and vibration tolerance.
