The CQB150-300S Series is an industry standard quarter-brick DC-DC converter, providing up to 150W of output power @ single output voltages of 5, 12, 15, 24, 28, 48VDC. It has a high input voltage range of 180 to 425VDC (300VDC nominal) and 3000VAC reinforce isolation between input and output.
High efficiency up to 89%, allowing 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 system applications.
The standard control functions include remote on/off (positive or negative) and 80-110% adjustable output voltage. Fully protected against input UVLO (under voltage lock out), input over-voltage, output over-current, output over-voltage and over-temperature and continuous short circuit conditions.
All models are highly suitable for distributed power architectures, telecommunications, servers, base station, battery operated equipment, and industrial applications.
With over 80 years designing, manufacturing and supplying power supplies for some of the most demanding applications, Gresham has a strong reputation for service and support.
We offer a wide range of both standard and custom power supplies with many items readily available from stock.
