Many rack-mounted power systems and power supplies are specified as being 1U, 2U, 3U, etc. What does this mean? For electronic equipment racks (e.g., 19 or 23 inches wide), the term 1U is used to define one rack unit of height. 3U height would be 3 x 1.75” = 5.25-inches. It should be noted that the 1U, 2U, 3U, etc., heights are maximum dimensions.
Each module fits into a rack with a specific U height, such as 3U, 4U, or 5U — depending on its capacity. This design is widely used for commercial and industrial battery systems, including 5U rack batteries that offer high energy density in a compact footprint.
So a 1U high enclosure-mountable power supply needs to be shorter than 1.75-inches; a 2U enclosure-mountable supply needs to be shorter than 3.5-inches, and so forth (see Photo #2). Photo #1: This 19” rack-mountable power system can hold up to 3 plug-in, hot-swap and redundant power supplies.
1U equals 1.75 inches (or 44.45 mm), making it easy to size and organize hardware in a consistent, stackable way. Whether you're building a server setup or an energy storage system, understanding this unit helps you choose the right hardware. How Tall Is a Rack Unit? A Quick Breakdown Each rack U size represents a multiple of 1.75 inches.
3U height would be 3 x 1.75” = 5.25-inches. It should be noted that the 1U, 2U, 3U, etc., heights are maximum dimensions. In order to allow for mechanical tolerances and to provide some space between panels, typically, for each 1U of height manufacturers may deduct about 0.03” (see Photo #1).
