Enclosed Frames

Ensure safeguarding against environmental factors with a fully enclosed power supply. Unlike open frame designs, these power supplies are housed in a protective box or frame.

Enclosed power supplies offer protection against electromagnetic interference and acts as a physical barrier to prevent electrical shock or injury.

MEAN WELL offers a wide range of closed frame power supplies in various sizes, usually proportional to the power output of the supply. Some models include features: 5G vibration testing, built-in power factor correction function, built-in remote sense and on/off control functions, parallel function, and the ability to withstand 300VAC surge input for 5 seconds.

There are many types of switching power supplies, the most common are available in single, double, triple, or quadruple output options.

Single Rail

Single rail enclosed power supplies from MEAN WELL are the most popular type available. These units provide a single output voltage to another in a controlled and efficient manner, making it suitable for a wide range of applications. Standard output voltages are available in 3.3V, 5V, 12V, 15V, 24V, and 48V. The power output of MEAN WELL's enclosed power supplies ranges from low-wattage to high-power models (up to 1000W or more for certain series).

ADM stocks a range of single rail enclosed power supplies from MEAN WELL including HRP, PSP, LRS, RSP, and UHP series. Click here to view the single rail enclosed range.

Dual Rail

MEAN WELL’s dual rail enclosed power supplies allows power to flow in both directions between the source and load. This bidirectional capability provides increased efficiency and reliability if one power source fails, the other source can compensate. Dual rail power supplies are commonly used in industrial and manufacturing environments, data centres and telecommunications systems.

Triple Rail

The triple rail enclosed power supply is an efficient and flexible solution for advanced electronic systems, providing three distinct output voltages that can be easily switched using control signals. Its primary advantage lies in its adaptability, allowing users to select the appropriate voltage for their specific applications without needing additional power supplies or voltage regulators.

Triple rail power supplies provide three independent output voltages in one enclosure. These are ideal for complex systems that require multiple voltage levels.

Quad Rail

Quad rail closed frame power supplies offer four output voltages in a single unit. These are designed for sophisticated systems that demand multiple voltage levels. MEAN WELL offers RQ, QP and UMP series in the multi rail power supply range. To browse the quad rail enclosed power supply range click here.

With MEAN WELL’s single and multi-rail solutions, including dual, triple, and quad rail power supplies, users can choose which is most effective to power their application. If you need help choosing an enclosed power supply, contact ADM here.
