PART NUMBER: VWRAT2
DESCRIPTION: dc-dc converter
description
features
Designed to convert a wide input
voltage range into an isolated
regulated voltage, the
·wide (2:1) input range
·regulated
·dual voltage output
·I/O isolation: 1500 V dc
·no heatsink required
·short circuit protection
·MTBF >1,000,000 hours
VWRAT2-SMT series is well
suited for providing board-mount
local supplies in a wide range of
applications, including mixed
analog/digital circuits, test &
measurement equip.,
·temperature range: -40°C~+85°C
process/machine controls,
datacom/telecom fields, etc...
