Buffer power supplies

What are buffer power supplies? 

Buffer power supplies are devices that provide continuous power for systems such as alarms, monitoring or building automation. They work in such a way that, in the event of a mains power failure, they automatically switch over to battery power, so that your devices operate without interruption. 

What are the types of buffer power supplies? 

1. Buffer power supplies 12V/13.8V - are the most popular power supplies, used in alarm systems, monitoring and other low-voltage applications. They provide stable power to devices and automatically switch to emergency power when needed. 

2. Buffer power supplies 24V/27.6V - designed to supply power to more demanding systems that operate at higher voltages. Used in professional installations such as extensive monitoring systems or large telecommunications installations. 

How do I choose the right buffer power supply? 

1. Output power and voltage: The choice of buffer power supply depends primarily on the power and voltage requirements of the system you want to power. If you need a power supply for standard 12V equipment, a good choice would be Extralink AD-155A 155W. For less demanding applications where less power is sufficient, Extralink AD-55A of 55W will be adequate. 

2. Additional features and parameters: Buffer power supplies can be equipped with additional features, such as the ability to connect emergency batteries (some models require batteries to be purchased separately) or various mounting options. Pay attention to the dimensions and material of the enclosure, especially if you plan to mount in a confined space or in difficult conditions.  

3. Power supply for larger systems: If your installation requires a higher voltage, such as 24V, choose a buffer power supply to ensure adequate power and stability. Extralink SCP-50-24 offers 27.6V and 50W of power, which is ideal for more advanced systems requiring a stable power supply. 

4. Consider additional features: Look out for additional options, such as the ability to connect emergency batteries, which can be crucial in the event of power cuts.
