DIN Rail DC/DC Converter: 40W

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

Packaged in a low profile design measuring 91x53x57mm. The range is designed to offer additional voltages in DIN rail power systems, provide isolated outputs & noise immunity or support battery powered or battery backed applications.

Capable of operating over a wide temperature range from – 40 to + 70 degrees C, the DDC series delivers full power up to +50 degrees C and suits use in most environments where the applications require extended operating temperatures.

The front panel hosts two LEDs that provide indication of DC ON & DC low status along with access to screw terminals for input and output connections. Added extra features include Remote ON/OFF control and output adjustment via potentiometer. The DDC series provides convenience for the system designer in accommodating additional supply voltages from a single DIN rail installation rather than having to incorporate multiple power supply formats.
