The QADA-18-5-0802 desktop wall adapter is an AC DC converter that bridges a variety of electrical systems, allowing systems to power up, enabling long-term power stability and efficiency.

The QADA-18-5-0802 AC DC desktop wall adaptor features a universal input voltage which can range from 100-240 volts with a frequency of 50/60 Hertz. This adaptor is equipped with a variety of output types, ranging from 1A to 5A with a voltage range of 90V-240V. The adaptor also features protection against short circuit, over-voltage, over-load, and even brief inrush currents. The QADA-18-5-0802 adaptor is also designed with an USA plug for easy installation.

The AC DC desktop wall adapter is a necessary component for applications where there is a need to maintain a regular voltage and current flow to power up various electrical components. These adapters can be used in a wide range of applications, including; laser and LED lighting systems, home theater systems, game consoles, home automation systems, medical equipment, all-in-one computers, and industrial process controllers.

The working principle of the QADA-18-5-0802 AC DC desktop wall adapter is to convert and regulate the alternating current (AC) voltage from a power outlet to a suitable direct current (DC) voltage that the device in use needs, for example 12 volts. The primary components inside the AC DC wall adapter are a power transformer, switching transistors, control circuits and an electrolytic capacitor.

For the input side of the AC DC wall adapter, it will draw power from the AC outlet and pass it through a power transformer to reduce the voltage to an acceptable level. The output side of the adapter uses two power switching transistors and a control circuit to generate a pulse-width-modulated (PWM) electric signal. The PWM signal in turn is used to control the current from the transformer to the output terminal.

The output voltage from the AC DC wall adapter is then regulated by an electrolytic capacitor. The capacitor filters out the noise and adjusts the output voltage of the adapter. This provides smoother output voltage and prevents short circuits and overvoltages from occurring.

In addition, the AC DC wall adapter is also equipped with over-current protection. This component serves to protect the device from drawing too much current, which could possibly cause the device to damage and overheat.

The QADA-18-5-0802 AC DC desktop wall adapter is an essential component in providing a steady output voltage and current for any system it is connected to. The universal input of this adapter combined with its various output types makes it the ideal choice for any application requiring efficient and reliable power conversion and voltage regulation.
