Nowadays, as people's awareness of safety and precautions has increased, the application of intelligent systems has been popularized in various fields, such as office buildings, commercial buildings, schools, and residential communities. As a subsystem of the security system, the access control system occupies an indispensable position in people's homes and work.
The power supply of the access control system is the basis for ensuring the stable operation of the entire access control system. The selection of the power supply can directly affect the operation of the system, and it can also reflect the engineering company's ability to control the quality of the project. In view of this detail of the power supply selection of the access control system, combined with the actual engineering experience, the items that should be paid attention to when selecting the power supply of the access control system are summarized, and there is no need to worry about the power supply selection.
First of all, in order to prescribe the right remedy, we should first understand what impact the power supply of the access control system may have:
1. The service life problem, after a period of use, the system will have the phenomenon of insufficient power supply;
2. Climatic problems, such as thunderstorms, hot and cold climates, etc. may fail, especially large-scale power failures are more likely to occur in thunderstorms;
3. The power supply is burned out due to the short circuit of the circuit caused by the construction process and other reasons;
4. There are problems with backup power equipment, and the battery is often broken, and it does not have the ability to maintain the normal operation of the system when the power is cut off.
In view of the above problems caused by the power supply, the following suggestions are made when choosing the power supply of the access control system:
The actual output power of the power supply
When purchasing a power supply, pay special attention to the nominal value of the power supply, and it is best to test the actual parameters on the spot, otherwise it will affect the normal and stable operation of the access control system.
Effective lightning protection
Depending on the specific location of the project, the installation environment of the access control system equipment is different, and the lines connected to the power supply will inevitably appear outdoors. Therefore, the power supply is required to have extremely strong and effective protection measures for lightning protection.
Wide temperature range
When choosing a power supply product, you should choose according to your own installation environment, so as to ensure the reliability of the system power supply.
Wide voltage range
Mains voltage fluctuations often occur, either high or low. Therefore, the power supply must be able to adapt to a wide range of mains voltage fluctuations, and the output voltage can be stable at 12V, to avoid unstable power supply caused by mains voltage fluctuations and affect the normal and stable operation of the video access control alarm system.
