APPLICATION
The CHB300W-110S series of DC-DC converters offers 300 watts of output power with single output voltages of 5, 12, 24, 28, 48VDC in and industry standard half-brick. It has a wide (4:1) input voltage range of 43 to 160VDC (110VDC nominal) and 3000VDC basic isolation.
Compliant with EN50155, EN45545, EN50121-3-2. High efficiency up to 91%, 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 systems.
The standard control functions include remote on/off (positive or negative) and +10%, -10% 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.
The CHB300W-110S series is designed primarily for common railway applications of 72V, 96V, 110V nominal voltage and also suitable for distributed power architectures, telecommunications, battery operated equipment and industrial applications.
