Ultra slim DIN rail power supplies

Louise Smyth

XP Power has launched a series of highly efficient ultra slim AC-DC power supplies that can be mounted on a DIN rail in factory automation, process control and various other industrial applications.

The DPC supplies accept a universal input range from 90 to 264 VAC without the need for any input selector switches.

Taking up significantly less space on a rail by being up to 44% slimmer than current generation DIN rail power supplies, the 30W DPC30 measures just 90.0 x 100.0 x 22.5mm (3.6 x 3.94 x 0.89 inches), while the 50W DPC50 measures 90.0 x 100.0 x 30.0mm (3.6 x 3.94 x 1.18 inches) and the 70W DPC70 measures only 90.0 x 100.0 x 40.5mm (3.6 x 3.95 x 1.59 inches).

Offering all the popular nominal output voltages from + 5 to + 48 VDC, the single output can be adjusted up to + 30% of stated nominal, model dependant, in order to accommodate non-standard voltage requirements or to make up for line losses.

All models feature a green LED to indicate output on.

These energy efficient supplies have typical efficiency ratings of 86 % (DPC30), 87 % (DPC50) and 89 % (DPC70). Both the DPC30 and DPC50 achieve a very low no load in-out power of 300mW with the DPC70 under 500mW.

The full output power is delivered across the input voltage range 100 – 264 VAC and at – 25 to + 50 C without the need to derate the units.

The operating temperature range of the series extends up to + 70C.

The DPC series meets EN/IEC 60950-1 safety approvals as well as EMC specifications EN55032 for class B conducted and radiated emissions.

The supplies also comply with the industrial control equipment standard UL508.

Use of screw terminals for both input and output connections provide a robust, quick and convenient means of installing the units.

The series is available from distributors or direct from XP Power and come with a 3-year warranty.
