XP Power announced the DPC series of DIN rail ac-dc power supplies. Available in 30-, 50- and 70-Watt single-output models, they all accept a universal input range from 90- to 264-Vac without the need for any input selector switches. Taking up significantly less space on the rail by being up to 44% slimmer than current generation DIN rail power supplies; the 30-Watt DPC30 measures 90.0 x 100.0 x 22.5 mm (3.6 x 3.94 x 0.89 inches). Also, the 50-Watt DPC50 measures 90.0 x 100.0 x 30.0 mm (3.6 x 3.94 x 1.18 inches) and the 70-Watt DPC70 measures 90.0 x 100.0 x 40.5 mm (3.6 x 3.95 x 1.59 inches).
Offering 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 no load power of <0.3 Watts, with the DPC70 meeting <0.5 Watts. The full output power is delivered across the input voltage range 100- to 264-Vac and at – 25 to + 50 degrees C without the need to derate the units. The operating temperature range of the series extends up to +70 degrees C.
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. Typical applications for the DPC series include factory automation, process control and various other industrial applications.
Use of screw terminals for both input and output connections provide a robust, quick and convenient means of installing the units. The DPC series is priced at $26.00 for 500 pcs orders of the 30 Watt model and is available from Allied Electronics, Digi-Key, Newark or direct from XP Power and come with a 3-year warranty.
