Tips for choosing an access control power supply

In the access control system, the power switch is the most susceptible to damage. So, how to choose the right access control power supply, let's take a look at the hot security network Xiaobian.

Tips for choosing an access control power supply: Design concept of access control switching power supply

Consideration should be given to the power supply's own parameter design, electrical design, electromagnetic compatibility design, thermal design, safety design, and three-proof design. Because even the slightest negligence in any aspect can lead to the collapse of the entire power supply, we should fully recognize the importance of reliability design of power products.

Tip 2: Choose the power supply mode

The deviation between the outputs of the centralized power supply system and the differential pressure caused by the different transmission distances reduce the quality of the power supply, and the application of a single power supply may cause system paralysis when the power supply fails. Therefore, the distributed power supply system can meet the requirements of high reliability equipment.

    Tip 3: Selecting the Access Control Power Supply: Screening of Main Components of Power Supply Equipment

1 The resistance is 100% tested at room temperature according to the technical conditions, and the rejects are rejected.

2 Ordinary capacitors are 100% tested at room temperature according to technical conditions, rejecting non-conforming products.

3 connectors sample and test various parameters according to technical conditions.

4 semiconductor devices are screened according to the following procedures: visual inspection → initial measurement → high temperature storage → high and low temperature impact → electric power aging → high temperature test → low temperature test → normal temperature test.

     Tip 4 of choosing an access control power supply: manufacturing quality issues

The failure caused by the quality problem is independent of the working stress. Unqualified quality can be eliminated by strict inspection. In engineering applications, mature products of fixed-point manufacturers should be used, and products that are not certified are not allowed. Product equipment can only be used by the machine when it meets the standards. The above is one of the points that should be paid attention to when selecting the access control power switch. The matters that should be paid attention to during the installation of the access control system are also one of the reasons that affect the service life of the product.
