Emerson Network Power Launches 24W External AC-DC Power Adapters

Emerson Network Power has launched its new external power adapter, the AD2412N3L (AD24). The 24W AD24 power adapter is the latest addition to Emerson’s portfolio of ac-dc power solutions. The company claims that the external adapter provides a flexible power solution with a compact form-factor for a wide variety of portable and desktop applications including instrumentation, telecommunications, test and measurement systems and computer peripherals.

The AD24 freestanding ac-dc power adapter produces a fully regulated 12V output and features a universal 90-264Vac input, enabling the product’s use anywhere in the world. The adapter, which is available with a 3-pin (type C14) IEC320 ac input receptacle with a safety-ground leakage current maximum of 250 µA, delivers dc output via a fixed cable fitted with a standard 2.5mm (5.5mm O.D.) barrel plug.

The adapter is designed to ensure high levels of efficiency (82% typical) and features switching regulators for switched-mode operation to comply with Energy Star and Blue Angel requirements. To increase operating flexibility, the AD24 power adapter can operate at full load in a wide range of ambient temperatures without de-rating - from -5 to +50°C - compared to typical adapters. The adapter also features a built-in EMI filter and meets rigorous EN55022-B and FCC part 15 Level B EMC standards for conducted noise.

The AD24’s automatic recovery features protect the adapter against overvoltage and overpower conditions. The adapter also meets K.21 surge certification and has a high calculated MTBF of 850,000 full-load hours at 25°C ambient. In addition, the product has achieved a best-in-class safety approval profile, including UL/CSA 60950-1, TUV EN/IEC60950-1, CE Mark LVD & EMC and CCC certification.

Emerson Network Power’s AD24 power adapters are available for immediate delivery. Standard lead-time is stock to eight weeks and pricing starts at US$14.95 in OEM quantities.
