High-Voltage Input 300W DC-DC Converters
Cincon Electronics Corp has introduced the CHB300-300S-CMFC(D) series of 300W chassis-mount dc-dc converters. With high input range of 180- to 425-Vdc (300V nominal), this new product offers single-outputs of 5-, 12-, 24-, 28-, and 48-Vdc and 3000Vac reinforced isolation.
These half-brick format dc-dc converters are designed primarily for common applications of 300V nominal voltage, suitable for distributed power architectures, telecommunications, battery operated equipment and industrial applications.
The CHB300-300S-CMFC(D) series has a very low no load power consumption requirement of 10mA. Efficiency can go as high as 90%, and the case operating temperature is -40°C to 100°C.
The standard control functions include remote on/off (positive or negative) and -20~+10% adjustable output voltage. The chassis structure offers built-in EMI EN55032 (EN55022) filters, and meet EN45545-2 requirements. Also, it meets UL60950-1 2nd (Reinforced Insulation) Approval for DC Modules.
These dc-dc converters are fully protected against input UVLO (under voltage lock out), output over-current, output over-voltage and over-temperature and continuous short circuit conditions.
