Phoenix Contact Uno Power power supplies for compact cabinets

Click2Contact

The high power density Uno Power supply units from Phoenix Contact are designed to reliably supply loads of up to 100 W at 24 or 12 VDC in compact control cabinets. Low stand-by losses and highly efficient operation guarantee a high level of energy efficiency. The product range comprises five modules.

The three housings dimensioned 22.5/35/55 (w) x 90 (h) x 84 mm (d) take up very little space in the control cabinet. Power supply units providing 24 VDC output voltage are available in 30, 60 and 100 W versions; units for 12 V DC consumers are available in 30 and 55 W.

With low no-load losses of less than 0.3 W and an efficiency rating optimised for the entire operating range, the power supplies are very economical. With an efficiency of up to 90% at nominal load, only a small fraction of the electrical energy is converted into unwanted heat. The range is UL certified and features a wide-range input. Uno Power can handle input voltages from 85 to 264 VAC, resulting in reliable operation even in the event of mains grid voltage fluctuations. With an extended mains buffering time of up to 140 ms under full load and MTBFs exceeding 500,000 hours, these power supplies are said to be exceptionally reliable in operation. Outdoor use is also possible due to a broad operating temperature range of -25 to +70°C.
