The power supply for the router is an important component of any modern network system. Without it, the router is not able to fully function. It is the specifications of this component that this material will be devoted to. Recommendations will also be given regarding its configuration and selection.
main parameters
Any power supply for the router has the following main technical characteristics:
- DC output current in amperes. It can vary from 0.6 A to 2 A.
- The voltage supplied to the router. Its value can vary from 3.3 V to 9 V.
- Power adapter. It varies from 5 watts to 18 watts.
Circuitry device
Typically, any such adapter includes three main components. The first one is a transformer. With its help, the AC voltage decreases from 220 V to the required 5 or 9 V. Next in the chain is a rectifier bridge, consisting of 4 diodes. This element turns an alternating voltage into a constant. The last component in the conversion chain is a filter. It removes all unwanted ripple and stabilizes the output voltage.
Communications. Order of use
Any such adapter has the following communication list:
- A plug for connecting to the power supply network.
- A plug with a wire for supplying direct voltage to the router. The shape of this connector is individual for each manufacturer. In one case, for example, TP-Link solutions, its length can be 5.5 mm and diameter 3.5 mm. In other cases, the length of the plug is reduced to 2.5 mm, and the diameter to 1.3 mm. This connector is most commonly used by D-Link.
The power supply for the TP-Link router or any other manufacturer is connected for use as follows:
- We plug its plug into an AC outlet.
- Then the plug is installed in the socket of the network node.
There is no need to perform any additional manipulations with it.
Cost
At the moment, the power supply for the router can be purchased separately. This decision is justified only in the event of a breakdown. Repairing them is not recommended for the reason that it is not always possible to do this. And if you manage to return it to working condition, then the costs will be comparable with a new such adapter.
Depending on the power and quality, the cost of such a device can vary from 100 to 400 rubles. In the selection process, you need to pay attention to the power of the output current, voltage and plug, which must be compatible with the existing one.
Conclusion
It is best to use a complete power supply for the router. The manufacturer optimally selects such adapters to ensure maximum compatibility with the router. If it is broken, then it is better to purchase a new one. At the same time, it is advisable not to save and purchase exactly the power supply that is best suited. Otherwise, the access point may fail.
