Emerson Network Power Releases 72W External AC-DC Power Adapter

Emerson Network Power has expanded its portfolio of ac-dc power adapters with the launch of a 72W model. The new 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.

AD72 freestanding ac-dc power adapters are described as providing a very flexible, pre-approved power solution for a wide variety of portable and desktop applications, including instrumentation, test and measurement systems, telecommunications and computer peripherals. The adapter now includes three series of wall-mount units and eight series of freestanding units, and spans a power range of 3 to 100W.

The AD72 uses a high efficiency switch-mode design that complies with the Blue Angel requirement; it has a typical efficiency of 84%. 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 6 ft (1.85m) cable fitted with a standard 2.1mm right-angle barrel plug.

AD72 power adapters have a full load ambient operating temperature range of +5 to +40°C without de-rating. The adapters are comprehensively protected against overvoltage, overpower and short-circuit conditions, with automatic recovery. They are equipped with an internal EMI filter and comply with the rigorous 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.
