Access control power supply/charger equipment is specifically designed for use with door access control systems and accessories. To ensure the stability of the entire system.
There are two main types of door access control system power supply, linear power supply for access control system and switching access control power supplies.
1), linear power supply for access control system
Advantages: stable performance, no high-frequency ripple, and other interference.
Disadvantages: fever, low energy efficiency. There is no superpower supply to choose from.
2), Switching access control power supply
Advantages: It is convenient to use a high-power power supply for centralized power supply, and it shows better cost performance when raw materials and other prices continue to rise. Small size and lightweight.
Disadvantages: If the power quality is not good, the high-frequency ripple is not well controlled. For some access controllers with poor anti-interference ability, it is easy to cause the door controller to crash, resulting in the situation of not opening the door.
