Emerson Network Power has expanded its portfolio of ac-dc power adapters with the launch of a 78 watt model. The AD80 power adapter features a universal 90-264 Vac input and produces a single, fully regulated 24 V output capable of delivering up to 3.25 A continuously. AD80 freestanding ac-dc power adapters provide a pre-approved power solution for a wide variety of portable and desktop applications, including instrumentation, test and measurement systems, telecommunications and computer peripherals.
The AD80 uses a switch-mode design that complies with the One Watt Input Energy Star/Blue Angel requirement; it has a typical efficiency of 84%. The adapter is equipped with a 3-pin (type C14) IEC320 ac input receptacle, and features an internal, user accessible, ac input fuse. The dc output is provided via a cable fitted with a standard 2.5 mm I.D, 5.5 mm O.D. barrel plug. AD80 power adapters have a full load ambient operating temperature range of 0sC to +40sC without de-rating. The adapters are comprehensively protected against overvoltage, overcurrent and overpower conditions, with automatic recovery, and have a high demonstrated MTBF of more than 300,000 hours at full load and 25sC ambient.
