PSM11R-090

PSM11R-090 belongs to the AC DC desktop wall adapters. It comes with 3 adjustable output ranges, which can meet demands for most applications. With high efficiency, it is widely used in notebooks, POS systems, LED displays, 3D printers and other equipment.

The PSM11R-090 has 3 adjustable output ranges: 9V-12V, 15V-24V and DC 5V. The output voltage range can meet the various needs of customers. At the same time, equipped with wide input voltage range, the power adapter can be used no matter in the different regions, and the tolerant range can reach the 176Vac-264Vac.

In addition to adjustable output power, the PSM11R-090 also provides multiple protections like overload, short-circuit, overvoltage and overpower. When input voltage is beyond the normal range or output current beyond the rated range, these protections can make sure the adapter operate safely and has longer lifetime.

As to the working principle of PSM11R-090, it is based on AC to DC conversion. Internally, the power adapter contains a bridge rectifier, a filter capacitor and a linear regulator or a switching regulator. When the adapter is plugged in, the AC voltage will be converted to DC current and afterward the voltage will be regulated, which can ensure the stability of the output current.
