Many of our customers have inquired about the differences between Linear access control power supplies and Switch access control power supplies. This is because they want to make an informed decision and select the models that best fit their project requirements. Here, we have prepared a detailed comparison between these two types of power supplies to help you understand their distinctions and make a more suitable choice.

difference	Linear access control power supply	Switch access control power supply
common    sense	The linear access control power supply has a relatively stable output voltage with small ripple and little load interference. However, its efficiency is low and heat generation is large. Although it provides reliable voltage output and minimal disruption, its energy conversion is less efficient than some alternatives, requiring measures to manage heat for proper functioning. .	The switch access control power supply has high efficiency, low heat, and can provide large power output. But its output ripple is relatively large and may cause interference to some sensitive equipment. Although it has good power and energy-efficient features, in applications with sensitive electronics, additional measures may be needed to reduce ripple impact and ensure proper equipment operation.
Input	AC 180V-230V	AC 90-240V
Advantages	more stable in voltage	more power output
Output	12V 5A	12V 5A
Weight	1.9KG	1.5KG
standard       cartons	10pcs	10pcs

In summary, if you require a high-power access control power supply, such as those used in face recognition machines with temperature measurement functions, fingerprint devices, and the like, you may consider opting for 208CK.... On the other hand, if you only have ordinary access control and only need to manage a single door, then we recommend using PS-300. This way, you can select the most suitable power supply according to your specific access control requirements and usage scenarios, ensuring efficient and reliable operation of your access control system.
