•
•
Up to 30 Watts Output Power
Three Fully Isolated Outputs
The DVST series of high reliability DC-DC converters
contains internal EMI filtering and meets MIL-STD-
461C 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.
Wide Input Voltage Range: 15 to 50 Volts per
MIL-STD-704 with 80 Volt Transient for 1 sec
Internal Filter Meets MIL-STD-461C and MIL-
STD-461D Conducted Emissions Requirements
NO Use of Optoisolators
Undervoltage Lockout
Indefinite Short Circuit Protection
Current Limit Protection
Low Output Noise
Custom Versions Available
Low Profile (0.380 inches) Package
Military Environmental Screening Available
