Cincon CQB50W8 CMFC(D) 50W Isolated DC-DC Converters offer a wide (8:1) input voltage range of 9.5VDC to 75VDC and reinforced isolation of 3000VAC. These converters feature low no-load power consumption, making them an ideal solution for energy-critical systems, and an optional heat sink to extend the full power range of the unit. The CQB50W8 series is fully protected against input undervoltage lockout (UVLO), output overcurrent, output overvoltage, overtemperature, and continuous short circuit conditions. Cincon CQB50W8 CMFC(D) 50W Isolated DC-DC Converters are constructed for common railway applications of 24V, 36V, and 48V nominal voltages.
