PFB750-300S Series

Powerbox

750W 2:1 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. PFB750-300S Series is HVDC input version of the full brick offering enabling high voltage input from AC/DC front end circuit or high voltage DC bus. Due to high voltage input range, market leading power density and base plate cooling, the PFB750-300S Series converters are really handy for subsea ROV applications or any other application with long, high voltage power transmission cables. The rugged design and fully potted enclosure are also appreciated in electric vehicle applications and heavy machinery with high voltage lithium battery systems like forklifts and cranes, maining, agriculture, forestry and cleaning equipment, postal, delivery and civil safety vehicles, public transportation and so forth. HVDC bus is becoming more common also on large lighting and server installations with centralized rectifier.
