Cincon CQB50W8 50W Isolated DC-DC Converters

Cincon CQB50W8 50W Isolated DC-DC Converters provide up to 91% efficiency in an industry-standard quarter-brick size. These modules offer a 50W output power at single-output voltages of 12VDC, 15VDC, 24VDC, 28VDC, 48VDC. The converters feature a wide (8:1) input voltage range of 9VDC to 75VDC (36VDC nominal) and 3000VAC reinforced isolation. The converters have a case operating temperature range of -40°C to +105°C. An optional heat sink is available to extend the unit’s full power range. The Cincon CQB50W8 series complies with EN50155, EN45545, and EN50121-3-2 standards. The converters have a low no-load power consumption (10mA), making them an ideal solution for energy-critical systems.

Cincon CQB50W8 50W Isolated DC-DC Converters are primarily designed for common railway applications of 24V, 36V, and 48V nominal voltages. They are also suitable for distributed power architectures, telecommunications, battery-operated equipment, and industrial applications.
