Introduction to Open Frame

Open frame refers to a type of product design that features a non - enclosed or partially enclosed structure. In various industries such as electronics, open frame power supplies are widely used. These power supplies have an exposed circuit board without a fully sealed casing, which offers several advantages. They are often more cost - effective as they require less material for enclosure. They also provide better heat dissipation since the components are more exposed to the surrounding air, which can enhance the overall performance and lifespan of the power supply. In addition, open frame designs allow for easier customization and integration into different systems, making them a popular choice for many manufacturers.
