What are the physical dimensions of an On - line UPS?

Nov 06, 2025

Hey there! As a supplier of On-line UPS, I often get asked about the physical dimensions of these devices. It's a crucial aspect, especially when you're planning to install them in a specific space. In this blog, I'll break down everything you need to know about the physical dimensions of an On-line UPS.

First off, let's understand what an On-line UPS is. An On-line UPS is a type of uninterruptible power supply that provides continuous power to connected equipment by constantly converting AC power to DC and then back to AC. This ensures a stable and clean power source, protecting your devices from power surges, outages, and other electrical issues.

Now, when it comes to the physical dimensions of an On-line UPS, there are several factors to consider. The size of an On-line UPS can vary greatly depending on its capacity, the number of battery modules it can support, and the specific design of the unit.

Capacity and Size

The capacity of an On-line UPS is measured in volt - amperes (VA) or watts. Generally, the higher the capacity, the larger the physical size of the UPS. For small - scale applications, like powering a single computer or a few small devices, you can find On-line UPS units with capacities ranging from 500VA to 2000VA. These smaller units are usually compact and can easily fit on a desk or a small shelf.

For example, a 500VA On-line UPS might have dimensions of around 10 inches (length) x 6 inches (width) x 7 inches (height). It's relatively small and lightweight, making it ideal for home offices or small business setups.

On the other hand, for larger commercial or industrial applications, where you need to power multiple servers, networking equipment, or other high - power devices, you'll need a higher - capacity On-line UPS. Units with capacities of 5000VA or more can be quite large. A 10,000VA On-line UPS could have dimensions of 24 inches (length) x 20 inches (width) x 36 inches (height) or even larger. These big units are often installed in dedicated server rooms or equipment racks.

Battery Modules

Another factor that affects the physical dimensions of an On-line UPS is the number of battery modules it can support. Batteries are an essential part of a UPS as they store energy to provide power during outages. Some On-line UPS units come with built - in batteries, while others allow you to add external battery modules to increase the runtime.

If a UPS has a built - in battery, the size of the battery is incorporated into the overall dimensions of the unit. For example, a small On-line UPS with a built - in battery might be slightly larger than a similar - capacity unit without a battery to accommodate the battery compartment.

When it comes to external battery modules, each module adds to the overall size and weight of the UPS system. A standard battery module for a medium - sized On-line UPS could have dimensions of around 15 inches (length) x 8 inches (width) x 10 inches (height). If you need to add multiple battery modules to extend the runtime of your UPS, you'll need to have enough space to install them.

Design and Form Factor

The design and form factor of an On-line UPS also play a role in its physical dimensions. There are different types of form factors available, including tower and rack - mount designs.

Tower - style On-line UPS units are designed to stand upright on the floor or a flat surface. They are similar in shape to a small tower computer case. Tower units are often a good choice for small to medium - sized applications where you don't have a dedicated rack for equipment. They are easy to access and maintain, and you can place them in a corner or against a wall.

Rack - mount On-line UPS units, on the other hand, are designed to be installed in a standard equipment rack. These units are typically more compact in width and depth compared to tower units, as they are designed to fit within the standard rack dimensions. Rack - mount UPS units are commonly used in data centers and server rooms where space is at a premium, and equipment needs to be organized in a rack - based system.

For instance, a rack - mount On-line UPS with a capacity of 3000VA might have dimensions of 19 inches (width) x 3.5 inches (height) x 24 inches (depth), which allows it to fit neatly into a standard 19 - inch equipment rack.

Considerations for Installation

When planning to install an On-line UPS, it's important to take into account not only the physical dimensions of the unit itself but also the space required for ventilation and maintenance. On-line UPS units generate heat during operation, and proper ventilation is essential to prevent overheating.

You should leave at least a few inches of clearance around the UPS unit to allow for air circulation. For example, if you're installing a tower - style UPS, leave a few inches of space on the sides, back, and top of the unit. If it's a rack - mount UPS, make sure there is enough space between the unit and other equipment in the rack for proper airflow.

In addition to ventilation, you also need to consider the space required for maintenance. You'll need to be able to access the battery compartments, input and output connections, and other components of the UPS for routine checks and servicing. Make sure there is enough room to open the doors or panels of the UPS and to work safely inside the unit.
