AC/DC desktop and wall adapters are power conversion devices which transform AC line voltage from the wall outlet into safely usable levels to supply power to electronic products. SWI12-12-E-P5R is an AC to DC switching power adapter with a DC output of 12 volts, 12 amp and 150 watt built-in power supply with a standard P5 type barrel plug. It has been designed for sound systems, media players, DVD players, digital video cameras, monitors, and other small electronic tools and devices.

It is recommended that the SWI12-12-E-P5R be used with an input voltage of 100 to 240 VAC, a frequency of 50 to 60 Hz, and an operating temperature range from 0 to 60 degrees Celsius. This AC/DC mains power adapter has a tightly regulated 12 volts output and meets the highest international safety standards - featuring an over temperature and overload protection. Furthermore, it includes a low standby power consumption for increased efficiency and meets DOE Level VI efficiency standards.

The product is user-friendly, featuring an LED display to indicate the amount of the remaining power in the adapter. It also has an automatic power saving mode that helps to reduce energy costs and improve the environment. It has a lower ripple and noise level that provides a clean power source with no distortion or interference. In addition to this, the product comes with a worldwide safety approval, is CE, FCC and RoHS certified, and is UL/cUL safety approved.

The working principle of the SWI12-12-E-P5R is relatively simple and involves an AC-DC converter which transforms the AC mains voltage into regulated DC voltage. The switching power supply uses a high frequency switching transistor as the main source of power. This switching transistor operates at a frequency of roughly 50 to 60kHz and is triggered by a PWM control which amplifies the frequency of a signal from the reference wave input. This amplified signal is used to control the switching cycle, which then produces the desired output voltage. The P5 type barrel plug is connected to the output of the AC/DC power adapter and provides DC output at a constant voltage.

The SWI12-12-E-P5R is a highly reliable and efficient device to power different electronic products and provides a clean source of power with low noise and ripple level. This AC to DC desktop and wall adapter is also user-friendly and features various protections and safety certifications. Additionally, this product complies with the DOE Level VI energy efficiency requirements and helps to save energy and improve the environment.
