Emerson Network Power, a business of Emerson, has expanded its portfolio of AC/DC power adapters with the launch of a high-efficiency 72W model. The freestanding AC/DC power adapters provide a pre-approved power solution for a variety of portable and desktop applications including instrumentation, test and measurement systems, telecommunications and computer peripherals.

The AD72 power adapter features a universal 90-264Vac input, enabling it to be used anywhere in the world, and produces a single, fully regulated 16Vdc output capable of delivering up to 4.5A continuously. The power adapter uses a high-efficiency switch-mode design that complies with the Blue Angel requirement; it has a typical efficiency of 84 percent. The adapter is equipped with a 2-pin (type C8) IEC320 ac input receptacle and features an internal ac input fuse. The DC output is provided via a 6ft (1.85m) cable fitted with a standard 2.1mm right-angle barrel plug.

The power adapters provide a full load ambient operating temperature range of 5C to 40C without de-rating. The adapters are protected against overvoltage, overpower and short-circuit conditions with automatic recovery. They are equipped with an internal EMI filter and comply with the EN55022-B and FCC part 15 Level B EMC standards for conducted noise, and also meet applicable electromagnetic immunity standards including EN61000-4-2 and -4 levels 2. The power adapters also carry a comprehensive set of safety approvals including UL/CSA/NEMKO 60950-1.

Pricing starts at $35 in OEM quantities.

Availability: Standard delivery is from stock to eight weeks.
