DC/DC Product Specification th - 1/16 brick fully regulated DCDC converter. Rev 30.08.2012 AVD50 series 1 of 2 AVD50-48S3V3 th 1/16 brick Input voltage: 36-75V Single Output: 3.3V Rated power: 49.5W Product Description th The AVD50-48S3v3 is the latest high efficiency 1/16 brick. It operates from a wide input range of 36Vdc to 75Vdc and provides a regulated output voltage of 3.3Vdc. The output is rated to a power level up to 49.5Watts maximum. Its protection features include non latching OCP, OTP and OVP. It also has an enable pin on the primary side of the converter. The unit is an open frame design with baseplate option that is optimised for either contact-cooled applications or forced airflow applications. Special Features Specifications Feature -2:1 Wide input range Output power: 49.5W Super high efficiency: 92%(3.3V) -Optimised for High Functions: Remote control, trim function, Sense density, small space Input LVP, output OVP and OCP, OTP applications Open frame structure with base plate option.
