Delta DVST281255T-XXX High reliability dc-dc converter Datasheet

DVST2800T Series
HIGH RELIABILITY
DC-DC CONVERTERS
DESCRIPTION
FEATURES
The DVST series of high reliability DC-DC converters
contains internal EMI filtering and meets MIL-STD461C and MIL-STD-461D for conducted emissions,
providing a one piece COTS solution for power
conversion applications. The DVST series is
operable over a wide (-55°C to +100°C) temperature
range with no power derating. Unique to the DVST
series is a magnetic feedback circuit that is radiation
immune. The three low noise outputs are fully
isolated from each other, allowing for maximum
flexibility in system design.
