Description

Designed to convert fixed volt- ages into an isolated voltage, the VESD2-DIP series is well suited for providing board-mount local supplies in a wide range of appli- cations, including mixed analog/digital circuits, test & measurement equip., process/machine controls, data- com/telecom fields, etc... The semi-regulated output can be followed by 3-terminal regulators to provide output protection, in addition to output regulation. Output Specifications Item Test conditions Min. Typ. Max.
