Switching Power Supply Related Technical Articles Switching Power Adapter Selection Considerations
Switching power adapter is generally used for voltage regulation and rectification and the use of power supply equipment, which is widely used in hotels, office buildings, office buildings and other large places and normal residential buildings and other places where people gather, then as a developer or property, management agencies, the choice of switching power adapter should pay attention to what matters?
First of all should pay attention to the selection of switching power adapter input voltage specifications, for commercial buildings generally higher power consumption, for the input power supply voltage is also higher, so then choose the switching power adapter to pay attention to the choice of a larger load capacity, so as not to cause a certain degree of safety accidents or power outages and other issues; Secondly, choose the right power, the output power is generally based on the needs of different places are also different, the principle requires that Need to choose the place where the power supply power 130% or more of the switching power adapter; Third, consider the load, now the switching power adapter has a variety of load methods, such as motor load, light bulb load, etc., choose to pay attention to the place of use of the power supply load, and choose to meet the place of use of the maximum load load in the boot moment, while preventing sudden shutdown caused by voltage back-up and other issues The fourth should consider the temperature of the switching power supply adapter in its working environment, the temperature caused by overloading or quite urgent cases occur from time to time, so before selecting the switching power supply adapter in the premises should pay attention to the temperature of the distribution room and the actual selection of the voltage load; the fifth is to pay attention to the functions contained in it, for the protection of the function of the general need to pay attention to the protection of the over-voltage, so as not to cause the boot instantaneous voltage load caused by the safety accidents. The fifth is to pay attention to the functions it contains. For the temperature protection can also ensure the normal use of the switching power adapter, to prevent causing fire and motor burnout and other accidents. Overload protection is also to meet the current place suddenly overload or overload caused by switching power adapter burnt or voltage back-up caused by accidents.
For the application function, due to the switching power adapter in recent years more and more humane, we choose to focus on the control circuit supporting the various functions, the signal function is to observe its normal use and sudden power outages, failures and other problems, so that we can find problems in time. Remote control function is to achieve the separation of man and machine, improve the safety of the normal power supply, reduce more safety accidents, telemetry function is also a new technology, mainly timely switching power adapter data and unstable current when the situation through text messages or other ways to send to the electrician, in order to facilitate the timely understanding of the unexpected events, provide solutions. For the general demand for voltage and power stability of the premises should also choose more suitable for the premises of the function, such as non-constant power function, in order to ensure that the switching power adapter in the fault can still be safe power supply of supporting functions; Finally, we should pay attention to the selection of switching power adapter whether it is through the electromagnetic authentication, whether it is in line with the safety regulations, which is also to provide the primary guarantee of safety.
