Powerbox

400W 4:1 Input Single Output DC/DC Converter

PFB Series regulated and isolated full brick DC/DC converters range from 400W up to 750W with 2:1 and 4:1 inputs. Operating temperature from -40C up to 100C combined with conduction cooling enables the use of PFB converters in various industrial, transportation, defese and telecom indoor and outdoor applications. PFB400W is wide 4:1 input, high power density version of the full brick offering. The 9-36V input versions are usable on multi platform systems covering 12V, 24V and 28V bus voltages common in industrial and defense applications as well as multitude of transportation applications marine, railway, avionics and automotive secments. The 18-75V input version covers the 36V and 48V bus voltages common in industrial, railway and telecom applications. The PFB400W offers unmatched power density with the wide 4:1 low line input range.
