The UNO-PS/1AC/12DC/55W Single-Phase Industrial Power Supply is a rugged AC to DC Converter built to meet the high stability and efficiency expectations of industrial, machine automation and process control environments. This Switching (switch mode) Power Supply ensures a regulated output voltage even in the event of voltage fluctuations in the power supply network. With all required safety certifications to support ITE (Information Technology Equipment), ruggedized packaging, extended operating temperatures, high peak load capabilities and high isolation voltages, the UNO Industrial Power Supply is designed to meet the needs of your industrial application. Industrial operating temperature of -25°C to +70°C Equipment found in traffic management, oil and gas pipelines, weather tracking, industrial and outdoor applications must function in temperatures that cannot be supported by a commercial power supplies. With an operating temperature of -25°C to +70°C, the UNO-PS/1AC/12DC/55W Single-Phase Industrial Power Supply is ideal for use with equipment subjected to harsh environments and severe temperatures. High efficiency up to 88% and no load power consumption <0.3W Compared with other products on the market, the UNO Industrial Power Supply provides excellent energy savings. With a very low no load power consumption (below .3 W) and 88% efficiency at nominal load, just a small amount of electrical energy is converted into undesired heat energy making this a very ECO friendly power supply. Ideal application environments for an UNO-PS/1AC/12DC/55W Single-Phase DIN Rail Power Supply DIN Rail Power Supply automated production process industrial control, automation, assembly, and test equipment building control, security and surveillance, and climate control systems. power countless industrial automation devices such as sensors, controllers and valves
