How to Select the Power Supply of Access Control System- TigerWong

As we all know, access control system requires high stability of power supply. It can be said that if you need stable operation of access control system, good power supply is essential. So what are our requirements for power supply? Here we mainly focus on the following aspects. 1. Power supply power. We are not only required to achieve power, but to achieve stable power and stable current output. Test method: test the actual output current and voltage of the power supply through a multimeter to see whether the output voltage and current can be at the rated output value. 2. Overload protection. Short circuit protection function, which is mainly used to prevent loss caused by unstable voltage or wrong line connection; Test method: check whether the manual has this function first, and if so, conduct wiring test. 3. Open circuit protection. Here, the open circuit protection can automatically cut off other power supplies, such as cameras, when using the battery power supply, so as to ensure the basic operation of access control. Test method: check whether the manual has this function first, and if so, conduct wiring test. 4. Charge and discharge management. Constant current charging ensures the power supply of other front-end equipment, prevents overcharge and discharge of the battery, and prolongs the service life of the battery; Test method: test the actual output current and voltage of the power supply through a multimeter to see whether the output voltage and current can be at the rated output value. 5. Isolation function. Multiple circuit outputs, and the failure of one circuit will not affect the normal operation of access control. Test method: Here we can judge whether there is multi-channel output by the number of output ports of the power supply. We have introduced the type selection test of access control system power supply. We hope it will be helpful to you.
