CN-A series, 30 to 200W 24Vdc input, railway isolated DC-DC converters with a compact quarter brick and half brick design (CN30A - 100A: 36.8 x 12.7 x 57.9mm, CN200A: 61 x 12.7 x 57.9mm) that uses less PCB space, a wide input voltage range of 60 to 160 Vdc and full regulation. These 30 to 200W railway isolated DC-DC converters are compliant with the applicable railway standards and are designed for harsh environments, meeting the shock and vibration requirements of IEC61373 Category 1 Class B. A true useable power from -40 to +100°C without derating can be provided by these railway isolated DC-DC converters which are base-plate cooled, they can also offer up to 88% efficiency and up to 4.2A useable output current. Typical uses for these railway isolated DC-DC power modules include battery powered railway systems such as rolling stock and fixed installations, power plants and customer power supplies.
