APPLICATION
The CHB300 300S Series is an industry standard halfbrick DC-DC converter, providing up to 300W of output power @ single output voltages of 5, 12, 24, 28, 48VDC. It has a high input voltage range of 180 to 425VDC (300VDC nominal) and reinforced with a 3000VAC isolation.
High efficiency up to 90%, allowing case operating temperature range of –40°C to 100°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), output over-current, output over-voltage and overtemperature and continuous short circuit conditions.
All models are highly suitable for distributed power architectures, telecommunications, servers, base station, battery operated equipment, and industrial applications.
