[ 2 YEAR WARRANTY ]
SDW30 SERIES
Single, dual and triple output
• 4:1 wide input voltage range
• 16 models available including 3.3V outputs
• Input reflected ripple according to CEPT
• Indefinite short circuit protection
• EN55022 conducted emissions level B
• Designed to meet EN60950 and IEC950
The SDW30 series of DC/DC converters supply up to 30 Watts of output power in a 3 x
2.56 x 0.81 inch package. The series features a 4:1 wide input voltage range which
ensures operation on semi-regulated distributed power voltages. Available in standard
single, dual and triple outputs, the series also offers 3.3V single output models for low
voltage logic applications. The SDW30 series complies with EN60950 for safety and also
complies with EN55022 level B conducted emissions. All models feature continuous
short circuit protection. The series boasts a high efficiency of typically 85% with tight
load and line regulation. The optimized thermal design and the copper case allow
operation in ambient temperatures of up to +70°C without derating. The features of the
SDW series make these converters ideally suited for on board logic and distributed
power systems.
