Low standby 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 x 90 x 84 mm (width x height x depth) take up very little space in the control cabinet. Power supply units providing 24 V DC output voltage are available in 30 W, 60 W, and 100 W versions; units for 12 V DC consumers are available in 30 W and 55 W.
All power supplies are highly energy efficient: Thanks to low no-load losses of less than 0.3 W and an efficiency rating optimized for the entire operating range, these power supplies are very economical compared to most commonly available units. 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, a crucial prerequisite for worldwide use. Uno Power can handle input voltages from 85 to 264 V AC, 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 (Mean Time Between Failure) exceeding 500,000 hours, these power supplies prove exceptionally reliable in operation. Outdoor use is also possible thanks to a broad operating temperature range of -25 °C to +70 °C.
