Differences and usage scenarios of shell type, rail type, and open frame type power supplies

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.15
In the field of electronics, power supply is a crucial component, and among them, shell type, rail type, and substrate type power supplies each have unique characteristics and application scenarios.

Shell type power supply


400W Switching Power Supply


Let's first talk about the shell type power supply, which is like a steady "Hercules". It has a sturdy casing, which not only provides good protection for internal components, but also ensures stable and reliable power output. Its heat dissipation performance is often excellent, and it can maintain good condition during long-term operation. It is often used in large equipment that has high requirements for power stability.

Rail type power supply


120W Din Rail Switching Power Supply


Next is the rail type power supply, just like a flexible "craftsman". It can be easily installed on standard rails, and this unique design makes it extremely convenient for installation and maintenance, saving a lot of time and energy. Especially suitable for industrial automation and other fields, it demonstrates its flexible advantages in compact spaces.

Open frame type power supply


5W Open Frame Switching Power Supply

Finally, there is the open frame type power supply, like a delicate "little elf". Directly integrated with circuit boards or substrates, it plays a crucial role in small electronic devices due to its high integration. Although compact in size, it also achieves the ultimate in space utilization, providing power support for devices that are extremely space demanding.

In short, shell type, rail type, and open frame type power supplies play important roles in the electronic world. According to different needs and scenarios, they all have irreplaceable positions, jointly promoting the continuous development and progress of electronic technology.
