Precautions for selecting switch power adapter
Switching power adapters are generally used for voltage stabilization and rectification of power equipment. They are widely used in large places such as hotels, office buildings, and office buildings, as well as in crowded areas such as normal residential buildings. Therefore, as developers or property management organizations, what precautions should be taken when selecting switching power adapters?
Firstly, attention should be paid to selecting the input voltage specifications of the switch power adapter. For commercial buildings, the power consumption is generally high, and the input power voltage is also high. Therefore, when selecting a switch power adapter, attention should be paid to selecting one with a larger load capacity to avoid certain safety accidents or power outages; Secondly, choose the appropriate power. The current output power generally varies according to the needs of different locations. In principle, it is necessary to choose a switching power adapter with a power supply power of 130% or more for the location; The third consideration is its load capacity. Nowadays, switch power adapters have multiple load modes, such as motor load, light bulb load, etc. When selecting, attention should be paid to the power load capacity used in the location, and the load capacity at the moment of startup should meet the maximum load capacity used in the location. At the same time, it is necessary to prevent voltage backflow and other problems caused by sudden shutdown; The fourth consideration should be given to the temperature of the switch power adapter in its working environment, which can cause overload or emergency situations. Therefore, before selecting a switch power adapter in a location, attention should be paid to the temperature of the distribution room and the actual load capacity of the selected voltage; The fifth is to pay attention to the functions it contains, and for protection functions, it is generally necessary to pay attention to overvoltage protection to avoid safety accidents caused by voltage load at the moment of startup. The protection of temperature can also ensure the normal use of the switch power adapter, preventing accidents such as fire and motor burnout. Overload protection is also to meet the requirements of accidents caused by sudden overload or overload in the current workplace, such as the burning of the switching power adapter or voltage reversal.
For application functions, due to the increasing humanization of switch power adapters in recent years, we have chosen to focus on various functions that can be matched with control circuits. The signal function is to observe its normal use and sudden power outages, faults, and other issues, so that we can detect problems in a timely manner. The remote control function achieves human-machine separation, improves safety during normal power supply, and reduces more safety accidents. The telemetry function is also a new technology, mainly to timely send the data of the switch power adapter and the real-time situation of unstable current to the electrician through SMS or other means, in order to facilitate their timely understanding of emergencies and provide solutions. For places that generally require stable voltage and electricity, it is also necessary to choose functions that are more suitable for the place, such as the continuous power function, to ensure that the switching power adapter can still safely supply power in the event of a fault; Finally, when choosing a switch power adapter, we should pay attention to whether it has passed electromagnetic certification and complies with safety regulations, which is also the primary guarantee of providing safety.
