AC DC Desktop, Wall Adapters

PSAA20R-033-R-C4 Application Field and Working Principle

PSAA20R-033-R-C4 is a latest offering from Mean Well enterprise, and is an AC DC Desktop and Wall Adapters, with AC input voltage ranges between 100 and 240V, and/or optional universal input voltage range 90~264V. This adapter has a rated output power of 33W and 27W respectively, and comes with metal enclosure and with protection features like short circuit, overload, over-voltage protection, and with 100% burn-in test.

PSAA20R-033-R-C4 is widely used in industrial and medical applications and supports both United States 3-prong plugs (type B) and international 3-prong plugs (type C) as its ports of connectivity. It also supports plug-in voltage selection switch for the look and feel of air flow.

Working Principle

PSAA20R-033-R-C4 has an internal circuit providing an electrical connection between an AC or DC power source and a DC load. The AC power input is converted to DC through rectifiers and then regulated with a power transistor. The PSAA20R-033-R-C4 adapter is then able to provide an adjustable and stable DC output power, by regulating the output voltage of the transistor with feedback loop. A constant current limiter, fan speed controller are also included in the adapter package.

PSAA20R-033-R-C4 AC DC Desktop and Wall Adapters are compact, efficient, and reliable solutions for powering industrial devices, medical equipment, consumer applications, and other electronic and electrical equipment.
