Selecting an Uninterruptible Power Supply UPS for Server Room
When it comes to critical infrastructure like designing a server room, there are two fundamentals to consider. The first is cooling, which involves sizing an air conditioning system to remove heat generated by the servers and create a comfortable working environment.The second step is to select and size an appropriate?UPS for Server Room.
UPS Systems Checklist
A UPS system is meant to offer consistent battery backup when there are no mains available. For a rack mount UPS system, the battery is normally internal, but it can also be stored in an exterior cabinet or tray. When choosing the correct uninterruptible power supply to protect your server room or datacentre, there are various factors to consider.
These are the three basic steps of choosing an?UPS for server room?environment. Once you are done with this assessment, there are other considerations that are to be determined.

Growth, Durability and Modular UPS Systems
The next stage is to determine the required amount of growth and resilience.It is recommended that the load profile be increased by 20% to allow for future expansion.This is true for mono-block UPS.If greater expansion is necessary, a mono block UPS must be expanded or one that can be fitted with parallel expansion for N+x resilience must be selected.
The built-in automatic bypass in an on-line UPS system protects against a single point of failure.The critical load is moved to the bypass supply without a gap in supply or downtime if the UPS experiences an overload or fault condition.Two or more UPS systems are installed in a robust UPS installation to share the load, with the potential capacity to support the entire load if necessary.
By design, modular UPS systems address both future expansion and durability.A modular UPS is made up of several standard-sized UPS modules housed in a standard-sized chassis.Modular UPSs are typically built in a tower format similar to server rack cabinets.They are designed to scale vertically and give a technique to make the most of the floor space in a server room or datacentre.To scale the arrangement horizontally, additional modular UPS frames can be placed in tandem.Modular?UPS for computers?or server room are also more likely to be three-phase and have larger power ratings.Single phase forms are also available in smaller sizes.Smaller modular UPS systems with self-contained frames that may be fitted within an existing server cabinet are also available.
As a result, one of the other important concerns for a UPS installation is the availability of space.Smaller UPS systems can be mounted as a floor standing tower alongside a server rack or as a rack mount cabinet within the rack.The larger the uninterruptible power supply, the more space it takes up, and this space grows as the battery duration requirement grows.For big server room applications, a separate UPS and battery room(s) may be required, along with a centralised rather than decentralised solution.
