IPhone video power supply
The power source means a small or slightly large electrical component that provides the electrical load needed by the structure to continue its operation. This component may be in a CCTV camera, TV, video iPhone, and similar devices. have In many cases, the malfunctioning of the iPhone is due to damage to the power supply board. For this reason, it is necessary to know what this device is in order to have a flawless device.
The task of the power supply on the iPhone video
This device consists of three parts: capacitor, transformer and diode bridge, each of which has specific responsibilities. Your available power supply can only perform these tasks properly if it has a sound design and quality components. These features are also present in products that are produced by reputable manufacturers.
Capacitor
A capacitor is a small electrical component that at first glance is made of two plates that are usually conductive. Of course, these two parts are separated by a thin insulator that allows electric charge to pass through it. This structure is designed in such a way that it eliminates the voltage fluctuation in the video iPhones, and prevents the creation of new fluctuations. Most of those who are active in installing, setting up and repairing all types of power supply for iPhone video first check the board capacitor because the possibility of capacitor failure is higher than other parts.
Trans
After that, checking the trans part is prioritized. Of course, this part of the iPhone power supply is also known as the power supply coil. These components usually have several bases that use multimeters to measure their correct performance. A board coil can first convert AC 220V to AC 12-24V, and then input it into the circuit. Of course, this parameter changes to DC voltage when it enters the circuit. If the trans of an iPhone image is healthy, no short circuit can be found in it. In addition, the first and second coils are not connected to each other in healthy samples.
Diode Bridge
Finally, it's Paul Diody's turn. This part is also known as rectifier. When this piece is placed in the circuit, it aligns the currents emitted from the diode bridge. This part also changes the AC voltage to DC and prevents the re-entering of the exited current into the circuit.

Linear power supply
Switching power supply
Uninterruptible Power Supply
Linear power supply
This type of power supply is designed in such a way that there is no disconnection and connection of current or switching. That is why it is called a linear source. This is despite the fact that there are parts such as transistors and diodes in the structure of this device. This device reduces the range of AC voltage to the required level to start. This process is done by a step-down transistor, and then it is aligned with a rectifier. In the next step, a capacitor filter is used. This filter easily removes the excess current ripples. It goes without saying that linear voltage regulators are also used in these items to further improve the efficiency of the structure.
Switching power supply
Unlike the previous example, the power supply of the iPhone video switching function is based on switching off and on the current through the transistor. This device has a number of high-frequency transistors that constantly switch the switch between off and on. With the continuation of this process, the current required for the iPhone to work will be created.
Uninterrupted power supply
The last example of an image iPhone power supply that can be reviewed is the uninterruptible power supply. In this case, the device is usually placed next to the video iPhone and is connected to the video iPhone with the help of some connectors (usually coaxial cables). These structures get their required current from the city electricity source. But if the power is cut in a certain situation or the voltage fluctuates, the power supply will cut off this voltage without interruption and deliver the energy needed by the iPhone to the connected device with the help of the electricity stored in its batteries. Uninterruptible power supply can prevent device failure and bring continuous (non-interrupted) activity to it.
Investigating the difference between simple power supply and switching
These two boards are functionally different. That's why they put the simple power supply in the audio iPhones, and the switching source in the video iPhones. It should be noted that the switching sample of these products structurally contains two numbers of transformers, each of which has two output pins. Despite these components, the switching power supply can provide different voltages for the iPhone video. In contrast to the simple example, these boards have a transformer, there are two input pins and two output pins. The voltage provided by these structures is suitable for audio iPhones.
