APPLICATION
The CHB300-300SXX-CMFC(D) series of chassis mountable DC-DC converters offers 300 watts of output power @ single output voltages of 5, 12, 24, 28, 48VDC. It has a wide (2:1) input voltage range of 180 to 425VDC (300VDC nominal) and 3000VAC renforced isolation.
High efficiency up to 90%, allowing case operating temperature range of –40°C to 100°C. An external heat sink is required to extend the full power range of the unit. Very low no load power consumption (10mA), an ideal solution for energy critical systems. Built-in EMI EN55032 (EN55022) filter. Meet EN45545.
The standard control functions include remote on/off (positive or negative) and +10%, -20% 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.
CHB300-300SXX-CMFC(D) series is designed primarily for common applications of 300V nominal voltage and also suitable for distributed power architectures, telecommunications, battery operated equipment and industrial applications.
