How to choose the access power supply for access control?

September 26 , 2020



1. Wide temperature adaptation range

 

Due to the relatively large temperature difference across the world. If the product does not have a wide range of adaptation to high and low temperatures, there is no way to guarantee the reliability of the system, especially the power supply, so when choosing a product, you should choose according to your own installation environment. Generally speaking, the temperature adaptation range is within -40 degrees to 85 degrees, which can meet the requirements.

   

2. Wide voltage adaptation range, stable power output

 

The input voltage fluctuates frequently, either high or low. Therefore, the power supply controller must be able to adapt to a wide range of input voltage fluctuations, and the output voltage can be stable at 12V to avoid unstable power supply caused by input voltage fluctuations and affect the normal and stable operation of the access control system.

 

3. Measure the actual output power of the power supply

 

Add a load corresponding to the output power of the power supply, run for more than 48 hours, use a multimeter to measure the actual output voltage and current of the power supply, and compare with the nominal value to check whether the output voltage is stable after the load is added and check the heat output Is it normal?

   

4. Intelligent charge and discharge management of the backup battery

 

Power outages occur in some areas, and access control is directly related to people's lives. It requires normal operation at all times. The backup power supply generally requires that the system can maintain normal operation for more than 4 to 6 hours after the power failure. The power supply has charge and discharge. Management function. The charging and discharging management function of the power supply is mainly to prevent the battery from overcharging and damaging the battery, and it will not be recharged after over-discharge, and the current supply of other devices will be reduced due to the excessive charging current, which will cause the system to be unstable.

  

5. Fault isolation to avoid damage to individual equipment and affect the overall stability of the system

   

Due to the diversity of the hardware equipment of the access control alarm system, it is bound to involve a power supply to supply power to multiple devices in a unified manner. At this time, it should be noted that the purchased power supply should have multiple output terminals for independent power supply and output, and the power supply is required to be able to intelligently judge the output Current, this can solve the problem of centralized power supply or when one output of the power supply fails, it will not affect the output of other power supplies. Even if the output of one power supply is directly short-circuited, it will not affect the output of other ports. Of course, the power supply will not be burned out due to a short-circuit of one port.
