Selection considerations for switching power adapter
Switching power adapters are generally used for power supply equipment used for voltage stabilization and rectification. They are widely used in large places such as hotels, office buildings, and office buildings, as well as in normal residential buildings and other crowded places. That said, what should you pay attention to when choosing a switching power adapter?
First of all, you should pay attention to the input voltage specification of the switching power adapter. For commercial buildings, the power consumption is generally large, and the input power voltage is also high. Therefore, when choosing a switching power adapter, pay attention to choosing a large load capacity to avoid certain safety hazards. Accidents or power outages and other issues; secondly, choose the appropriate power. The current output power is generally different according to the needs of different places. In principle, you need to choose a switching power adapter that requires more than 130% of the power supply in the place; thirdly, consider its load. The current switching power supply adapter has a variety of load methods, such as motor load, light bulb load, etc. When choosing, pay attention to the load of the power supply used in the place, and choose the load at the moment of starting up to meet the maximum load used in the place. Problems such as voltage backflow after shutdown; Fourth, the temperature of the switching power adapter in its working environment should be considered. Overload or emergency situations caused by the temperature may occur from time to time, so pay attention to the conditions of the power distribution room before choosing a switching power adapter in the place The temperature and the load of the actual selected voltage; the fifth is to pay attention to the functions it contains, and generally pay attention to the protection of overvoltage for the protection function, so as to avoid safety accidents caused by the voltage load at the moment of starting up. The temperature protection can also ensure the normal use of the switching power adapter and prevent accidents such as fire and motor burnout. The overload protection is also to meet the accidents caused by the sudden overload or overload of the current place, which causes the switching power supply adapter to burn out or the voltage to flow backward.
For application functions, since switching power supply adapters have become more and more user-friendly in recent years, we choose various functions that can focus on supporting the control circuit. The signal function is to observe its normal use, sudden power failure, failure and other problems, so that we can timely problem found. The remote control function realizes the separation of man and machine, improves the safety of normal power supply, and reduces more safety accidents. The telemetry function is also a new technology, mainly to timely transfer the data of the switching power adapter and the unstable current The situation is sent to the electrician through text messages or other methods, so as to facilitate them to understand emergencies in time and provide solutions. For places that generally require stable voltage and power, functions that are more suitable for the place should also be selected, such as the uninterruptible power supply function, to ensure that the switching power adapter can still supply power safely in the event of a fault; finally, we should pay attention to the selection of switching power adapters. Whether it has passed the electromagnetic certification and whether it complies with safety regulations is also the primary guarantee for providing safety.
