The essential information 

Power supplies are important components in an access control system. You need to have the right one. When designing your system, make sure you consider:

Output voltage: the power supply’s output voltage must be compatible with the specifications of the access control system. You should check the voltage required for all the components in a system, including card readers, electronic locks, and controller panels.

Power capacity: The power supply must be capable of providing enough power for all the components in the system. Check the power supply’s maximum capacity and ensure that it can handle the electric charge for the whole system.

Reliability: Power supplies must be reliable and resilient. They should operate effectively without interruption. Make sure you choose a high quality power supply to avoid outages and unexpected downtime.

Security features: Some access control systems need a power supply with additional security features. Your project might require protection against overvoltage, short circuits, or electrical overloads.

Two different types of power supplies for access control systems

Every access control power supply unit has a unique specification. Two of the key types to be aware of are:

  • Electrical power supply. These provide electricity to the access control system to operate the various components, such as card readers, electric strikes, and electro-magnetic locks. Electrical power supplies can be switch mode or linear.
  • Backup power supply. These combine an electrical power supply with a backup battery. In case of a power failure, the battery takes over supplying the system. This solution ensures that the system remains operational until the primary power supply is restored.

Common mistakes to avoid when choosing a power supply for access control systems

When selecting a power supply for an access control system, avoid mistakes by following these steps.

  • Choose a power supply that uses the same voltage as the access control system. It’s essential that all your components operate at the same voltage (usually 12V or 24V).
  • Think about how much power is required. The power supply must be capable of providing the required amperage for the entire access control system. Don’t forget to include peripheral components like card readers and electro-magnetic locks.
  • Plan a backup. We recommend using a backup power supply to ensure that the system remains operational even in the case of power failure.
  • Consider the installation environment. Factors such as installation location (indoor/outdoor), particularly high or low temperatures, and humidity can affect the operation of a power supply. Make sure the power supply you choose is suited to the environment in which you are installing it.
  • We recommend that you choose a power supply that comes with a long warranty period. The longer the warranty, the more peace of mind you and your customers have of a protected system.
