AC/DC Adapters Set Efficiency Benchmark

Described as high-efficiency components, the 50W AD50 and 100W AD100 series ac/dc power adapters specify typical power-conversion efficiencies of 80% and 90%, respectively. Both support a universal 90- to 264-Vac input. The AD50 adapters produce a single 12V output and can deliver up to 4.16A continuously while the AD100 models deliver a single 48V output and up to 2.08A continuously. The AD50 adapters are also available with medical safety approvals for non-patient contact and non-patient critical use. Both series employ switch-mode designs that comply with the One Watt Input Energy Star/Blue Angel requirement. The AD50 series is available with a three-pin (type C6) or two-pin (type C8) IEC320 ac input receptacle. Three-pin versions have a safety-ground leakage current of 300 µA maximum and two-pin versions specify 100 µA. In OEM quantities, prices for the AD50, AD50 medical, and AD100 start at $28, $ 32, and $56 each, respectively. EMERSON NETWORK POWER, St. Louis, MO. (800) 877-9222.
