Desktop, Wall Adapters have by far the widest application range of any of the categories of power products. The WR9QE500LCP-N(R6B) adapter is one of the many devices used for this purpose. In this article, the focus will be on describing the application field and working principle of this AC DC desktop wall adapter.

Firstly, let’s discuss the application field where the WR9QE500LCP-N(R6B) wall adapter is used. As stated earlier, desktop, wall adapters have by far the widest application range, and this one too is no different.

The WR9QE500LCP-N(R6B) wall adapter is an efficient and compact adapter that is designed to convert AC power to DC power at a nominal 12V-2.5A or 9V-3A output. It is ideally suited for powering many electronic devices such as laptops, tablets, mobile phones, cameras and game consoles. It is also suitable for indoor applications and can be used in places where the AC power rating is not very high as it has higher efficiency. Apart from that, the wall adapter has multiple protection measures against overload, over voltage, under voltage, and short circuit.

Now let’s move on to discussing the working principle of the WR9QE500LCP-N(R6B) wall adapter. This adapter is an AC/DC (Alternating Current to Direct Current) converter which works according to the Buck-Boost principle. This means that it takes an AC input and steps it down to lower voltage DC output.

The working of the wall adapter begins with the AC input first going through a rate of change of current transformer (RCCT). This is a primary line sensing device which is present to protect against faults or faults on the grid. After this, it passes through an optocoupler which converts the AC input to a low voltage DC signal.

The next stage of the wall adapter’s operation involves passing the low voltage DC signal through a PWM (Pulse Width Modulator) converter which changes the signal to an adjustable PWM signal. This signal is then passed through a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) which serves as a switch and helps to regulate the output voltage of the adapter. After this, the PWM signal is rectified and a feedback control is used to regulate the output voltage of the adapter. The output voltage is then smoothed and filtered through a LC (inductance capacitance) filter to reduce noise. Finally, the output voltage is ready to be used to power the electronic device.

In conclusion, the WR9QE500LCP-N(R6B) wall adapter is an efficient and compact AC DC adapter that is widely used for powering electronic devices. It is suitable for indoor applications and has multiple protection measures to protect against overload, over voltage, under voltage, and short circuits. Furthermore, it works according to the Buck-Boost principle and has a high degree of efficiency.
