IAS SERIES - 12 WATT
DESCRIPTION
IAS DC/DC converters provide up to 12 Watts of
output power in an industry standard package and
footprint. With a maximum case temperature of
100°C, the IAS is well suited for the most demanding
applications. The IAS features 1500 VDC isolation,
short circuit, and overtemperature protection, as well
as six-sided shielding. The IAS is available with
optional enable and voltage trim. Please see the IAD
series for dual output applications.
