It is often used by incorporating it into industrial equipment, which helps to prevent business stoppage in the event of an error and to safely shut down. Power supply methods using UPS include continuous commercial power supplies, line interactive power supplies, constant inverter power supplies, etc. The shape of the product is almost a rectangular parallelepiped, and vertical and horizontal types are the most common. There are also designs that are easy to install in narrow spaces, such as types that support both vertical and horizontal placement, an ultra-thin type, etc.
