Description

Designed to convert fixed volt - ages into an isolated volt age, the VEFT1-SMT dual series is well suited for providing board-mount local supplies in a wide range of applications, including mixed ana - log/digit al circuit s, test & meas - urement equip., process/machine controls, dat acom/telecom fields, etc... The semi-regulated output can be followed by 3-terminal regulators to provide output protection, in addition to output regulation. Output S pecifications Item Test conditions Min. Typ. Max.
