UPS

UPS Units are vital to keep your infrastructure running during power outages, making sure they stay operational and preventing data loss. They act as a backup power system to keep servers and infrastructures powered without interruption if the main power source fails. 

At ITinStock, we provide an assortment of high-quality UPS Units to support your infrastructure. Browse our selection from top brands, including APC, Eaton, Riello and more.

The Benefits of an Uninterruptable Power Supply

Uninterruptable Power Supplies (UPS) are critical for providing back-up power when there is power disruption. That alone means your servers can still be temporarily powered should you face any power cuts, voltage surges or any other power problems.

The main reason you want to keep your servers powered by a UPS is to avoid catastrophic data loss. Should your servers abruptly shut down without a temporary backup power supply, then they could be at risk of file corruption and data damage. That also means without a UPS, you’ll face critical downtime, resource spent on damage control and lost revenue.

A UPS actively conditions incoming power, which is useful as servers constantly face threats from voltage sags, surges and electrical noise. A UPS will filter out these electrical disturbances, helping to deliver clean, stable electricity to your sensitive equipment and extend server lifespan significantly.

Frequently Asked Questions

What Is the Purpose of a UPS Device for Servers?
A UPS for servers serves as critical protection against power disruptions that could otherwise cause catastrophic data loss and equipment damage. When your server loses power unexpectedly, it can result in corrupted databases, lost transactions, and significant operational downtime that impacts your business continuity. That means a UPS keeps providing power during power outages and fluctuations to ensure your servers don’t suddenly shut down and lose data. This gives you time to restore the power to your systems or back-up any critical data you may need.

How Do I Calculate the Right UPS Capacity for My Server Setup?
An undersized UPS won't protect your equipment when you need it most, whilst an oversized system adds unnecessary cost, so it’s important to get the right size. To do this, first calculate your total load by listing every device that will connect to the UPS, find the power rating for each in Watts, and add them all up to get your total power consumption. Then, convert this number into Volt-Amperes (VA) by dividing your total wattage by the power factor – typically 0.9 for modern server equipment. Then, add a slight buffer to ensure optimal UPS performance, with best practice being 20-30%. The final number will help you find the right UPS system, which are measured in VA.

How Long Will a UPS Keep My Servers Running During a Power Outage?
UPS runtime depends on several factors and can vary based on your configuration. They key factors are your battery capacity (measured in Ampere-hours or Ah, and voltage), its condition as they degrade over time, how many pieces of equipment are connected to draw power, and the temperature of the environment if not cool enough. A typical runtime in an office environment is around 15-30 minutes for a light load, but only 8-15 minutes otherwise, for example. Your primary concern during this short time is to make sure the servers are powered down safely and to back-up any critical data.

What Should I Consider When Buying a Refurbished Server UPS?
When purchasing a refurbished server UPS, battery condition is perhaps the most important consideration. Our batteries are generally replaced with new units during refurbishment, as batteries are the most failure-prone component. We also provide comprehensive load testing of all parts of the UPS and under actual operating conditions. We also stock plenty of known brands, such as APC, Eaton, Fujitsu and Riello, all of which provide quality units.

Another consideration is to check that the form factor matches your needs (rack-mount U-height, weight capacity, included mounting hardware). Refurbished units make excellent sense for enterprise businesses and SMEs looking to protect your servers at just a fraction of the cost of brand new.

How quickly can you deliver?
UK deliveries typically arrive next day via DHL Express or FedEx. We also offer European and international shipping with delivery timeframes varying by destination. Smaller pieces of IT hardware, such as components, ship quickly whilst larger items may require additional handling time. We are happy to discuss more specific delivery estimates based on your location. We can even same day items for the most urgent requirements!
