AC-DC power adapter

Emerson has further expanded its portfolio of AC-DC power adapters with the launch of a 72 W model.

The AD72 features a universal 90-264 VAC input enabling it to be used anywhere in the world and produces a single, fully regulated 16 VDC output capable of delivering up to 4.5 A continuously.

The freestanding adapters provide a flexible, pre-approved power solution for a wide variety of portable and desktop applications, including instrumentation, test and measurement systems, telecommunications and computer peripherals.

The adapter uses a high efficiency switchmode design that complies with the Blue Angel requirement; it has a typical efficiency of 84%. The adapter is equipped with a 2-pin (type C8) IEC320 AC input receptacle and features an internal AC input fuse.

The DC output is provided via a 1.85 m cable fitted with a standard 2.1 mm right-angle barrel plug.

The adapter has a full load ambient operating temperature range of +5° to +40°C without de-rating. The adapter is protected against overvoltage, overpower and short-circuit conditions, with automatic recovery and is equipped with an internal EMI filter and complies with EN55022-B and FCC Part 15 Level B EMC standards for conducted noise, and also meets applicable electromagnetic immunity standards, including EN61000-4-2 and -4 levels 2.

The adapter also carries a set of safety approvals, including UL/CSA/NEMKO 60950-1.
