The CQB75W8 series of DC-DC converters have a wide (8:1) input voltage range of 9 to 75VDC (36VDC nominal) covering 12V, 24V and 48V battery systems, and have 3000VAC reinforced isolation as standard.
The CQB75W8 series provides 75 watts of output power with single output voltages of 12, 15, 24, 28, 48VDC housed in an industry standard quarter-brick package. The CQB75W8 is compliant with EN50155, EN45545, EN50121-3-2. A high efficiency of up to 90%, allows case operating temperatures to range from -40°C to 105°C. Optional heat sinks are available to extend the full power range of the unit.
The CQB75W8 series has very low no load power consumption (10mA), making it an ideal solution for energy critical systems. Standard control functions include remote on/off (positive or negative) and +15%, -20% adjustable output voltages.
They are fully protected against input UVLO (under voltage lock out), output over-current, output over-voltage and over-temperature and continuous short circuit conditions.
The CQB75W8 series is suitable for distributed power architectures, telecommunications, battery operated equipment and industrial applications as well as railway applications operating from 24V, 36V, 48V supply voltage.
