Description
Designed to convert fixed voltages into
an isolated voltage, the VEFT1-SMT sin-
gle series is well suited for providing
board-mount local supplies in a wide
range of applications, including mixed
analog/digital circuits, test & measure-
ment equip., process/machine controls,
datacom/telecom fields, etc...
The semi-regulated output can be fol-
lowed by 3-terminal regulators to pro-
vide output protection, in addition to
output regulation.
