xxx Series
The DDC series is a range of DIN Rail mounting DC/DC converters designed to offer
additional voltages in AC input DIN Rail power systems, provide isolated outputs & noise
immunity or support battery powered or battery backed applications. With a 4:1 wide
input range the DDC series converters can be supplied by both a 12V or 24V nominal
input and offer output voltages between 5VDC and 24VDC
