Emerson Network Power today launched two new series of high efficiency external ac-dc power adapters. These latest additions to the company's rapidly-expanding portfolio of Astec ac-dc power adapters produce fully regulated outputs, and feature a universal 90-264 Vac input, enabling them to be used anywhere in the world. The new 50 watt AD50 series power adapters produce a single 12 V output and can deliver up to 4.16 A continuously, while the new 100 watt AD100 series models produce a single 48 V output and can deliver up to 2.08 A continuously.

Astec AD50 and AD100 series freestanding ac-dc power adapters provide a very flexible, pre-approved power solution for a wide variety of portable and desktop applications, including instrumentation, telecommunications, computer peripheral and test and measurement systems. The AD50 series adapters are also available with medical safety approvals for non-patient contact and non-patient critical use in low power medical, dental and laboratory applications.

All Astec AD50 and AD100 series ac-dc power adapters are high efficiency switch-mode designs that comply with the One Watt Input Energy Star/Blue Angel requirement. The AD50 series have a typical power conversion efficiency of 80%, while the AD100 series offer an even higher figure of 90%. The AD50 series adapters are available with a choice of a 3-pin (type C6) or 2-pin (type C8) IEC320 ac input receptacle, to accommodate customers' desired configuration of line cord. The 3-pin versions of the adapters have a safety-ground leakage current of 300 µA maximum, while the 2-pin versions offer an even lower figure of just 100 µA. The adapters' dc output is provided via a cable fitted with a standard 2.5 mm I.D, 5.5 mm O.D. barrel plug.

AD50 series power adapters have a full load ambient operating temperature range of 5šC to +40šC without de-rating, while the AD100 series offers a slightly wider operating range of 0šC to +40šC. All the adapters are comprehensively protected against overvoltage and overpower conditions, with automatic recovery, and have a high demonstrated MTBF of 300,000 hours at full load and 25šC ambient. They all comply with the rigorous EN55022-B and FCC part 15 Level B EMC standards for conducted noise and meet all applicable immunity standards, including EN61000-4-2, -3, -4, -5, -6, -8 and -11 levels 3. The power adapters also carry a comprehensive set of safety approvals, including UL/CSA 60950-1,VDE/CB EN60950-1 and CE Mark. The medical versions of the AD50 have the following certifications: UL/CSA60601-1, VDE EN60601-1 and CE Mark LVD.

Astec AD50 and AD100 series external power adapters are available for immediate delivery.
