Description

Designed to convert fixed volt-

ages into an isolated voltage, the

VAT2-SMT series is well suited for

providing board-mount local sup-

plies in a wide range of applica-

tions, including mixed analog/digi-

tal circuits, test & measurement

equip., process/machine controls,

datacom/telecom fields, etc...

The semi-regulated output can be

followed by 3-terminal regulators

to provide output protection, in

addition to output regulation.
