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.
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.
