APPLICATION
The CQB75-300S series of DC-DC converters offer 75 watts of output power in single output voltages of 5, 12, 15, 24, 48VDC within an industry standard quarter-brick. It has a wide input voltage range of 180 to 450VDC (300VDC nominal) and 3000VAC reinforced isolation.
The CQB75-300S series has a high efficiency of up to 90%, giving a case operating temperature range of –40°C to 105°C. An optional heat sink is available to extend the full power range of the unit. Very low no load power consumption (10mA), an ideal solution for energy critical systems.
The standard control functions include remote on/off (positive or negative) and +20%, -20% (Except for 5Vout) adjustable output voltage.
Fully protected against input UVLO (under voltage lock out), output over-current, output over-voltage and overtemperature and continuous short circuit conditions.
CQB75-300S series is compliant with EN55032 (EMC), EN45545 (Fire and Smoke) making it highly suited to distributed power architectures, telecommunications, servers, base station, battery operated equipment, and industrial applications.
