Product Description
The AVO100B-48S3V3 is the latest high efficiency 1/8^th 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 99Watts 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 base-plate option that is optimised for either contact-cooled applications or
forced airflow applications.
