The Astec AD50 and AD100 series freestanding AC/DC power adapters provide a very flexible, pre-approved power solution for 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 nonpatient contact and nonpatient 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 has a typical power conversion efficiency of 80%, while the AD100 series offers an even higher figure of 90%.
The AD50 series adapters are available with a choice of a three-pin (type C6) or two-pin (type C8) IEC320 AC input receptacle, to accommodate customers' desired configuration of line cord.
The three-pin versions of the adapters have a safety-ground leakage current of 300uA maximum, while the two-pin versions offer a lower figure of 100uA.
The adapters' DC output is provided via a cable fitted with a standard 2.5mm ID, 5.5mm OD barrel plug.
All the adapters are protected against overvoltage and overpower conditions, with automatic recovery and have an MTBF of 300,000 hours at full load and 25C ambient.
They all comply with 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.
