DIN-rail DC-DC converters offer a wide input and noise immunity for industrial needs

Aimed at industrial applications, XP Power has introduced the DDC15 and DDC30 series of low-profile 15W and 30W DIN-rail format DC-DC converters. The range is designed to offer additional voltages in DIN-rail power systems, provide isolated outputs and noise immunity or support battery-powered or battery-backed applications. The single output converters accommodate the wide 4:1 input range from 9 – 36VDC suiting a 12 or 24VDC nominal input. Both series are available with a choice of a 5, 9, 12, 15 or 24VDC nominal output. Additionally, the DDC15 model is available with a 3.3 VDC output. Input to output isolation is 1500VDC. Occupying less DIN rail space than similar units available on the market, these slim compact convection cooled units measure just 91mm x 56.5mm x 18mm for the DDC15 and 91mm x 56.5mm x 35mm for the DDC30. Capable of operating over a wide temperature range from -40C to +70C, the DDC series delivers full power up to +50C and suits use in most environments where the applications require extended operating temperatures. The DDC15 and DDC30 converters have internationally-recognized safety approvals for UL508 (industrial control equipment), and IT approvals per EN60950-1 A12:2011 and IEC60950-1 +A1:2009 .The units also meet the Class B EN55022 specification for both radiated and conducted emissions without the need for any additional filtering components saving both extra cost and footprint. The front panel hosts two LEDs that provide indication of DC input status along with access to screw terminals for input and output connections. The DDC30 front panel includes a potentiometer for output voltage adjustment. 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, says the company.
