How Selecting the Right UPS Can Boost Data Centre Efficiency

How Selecting the Right UPS Can Boost Data Centre Efficiency

For companies that rely on data centres, down time is simply unacceptable. Regardless of why the power goes down, whether the problem stems from a natural or a man made cause, customers around the world still need service. When a company’s data centre goes down, so does their ability to take care of business.

When paired with a generator, an uninterrupted power supply (or UPS) system creates an essential backup service that can keep a business, and its access to important computer services, running no matter what. This solution can also protect against potentially dangerous power fluctuations from the grid itself.

Since the market offers a wide range of different UPS products, businesses need to work with a provider with experience in distribution and installation. These experienced professionals help business clients to acquire systems that not only meet their short term needs, but also scale alongside the business over time.

What a UPS Does

Companies might decide to use UPS systems for a few different reasons. Firstly, the solution can provide a safe transition to shutdown mode for vital and fragile data centre systems, or other business-critical computer systems. When paired with a generator, a UPS provides a smooth transition to in-house power systems when the power shuts down. Most UPS systems also have built in surge suppressors that protect vital systems from power surges that can take place, especially when the power grid shuts down and comes back on.

A UPS system must run constantly alongside of other equipment to monitor the power supply and act when necessary. This makes efficiency a necessity when choosing the right system.

The Importance of UPS Efficiency

UPS efficiency refers to how much power it requires to operate during normal periods of grid monitoring and other functions but it also means how much energy you will also use to cool the waste heat generated by the UPS. Many UPS systems range between 92 and 95 percent efficiency, but sometimes this can go up to 99 percent. Also, the efficiency ratings cover best possible operating conditions when using a full load. All UPS efficiencies decline when the system operates at less than a full load and users should to remember that upfront higher costs (capex) in more efficient UPS solutions can be quickly saved through cheaper in life energy usage (opex), the pay back period can be in as littel as 1-2 years in some cases even though the price difference can appear substantial.

UPS efficiency can have a powerful impact on a company bottom line. The more inefficient the system, the higher it will cost a company on its power bill. When choosing a UPS system, companies should make sure to choose one that meets all of their needs, yet also offers the best possible efficiency.

Three Examples of Efficient UPS Devices

The Eaton 93 PM UPS offers a modern system with both vertical and horizontal scalability. It also utilises a double conversion system that regulates the flow of electricity, ensuring a safe and consistent supply of power to equipment. “Double conversion” refers to the way in which it takes AC power, runs it through a DC converter, then coverts back again to AC. This process can even out surges that may otherwise damage sensitive equipment.

With an efficiency of 99% in ESS or upto 97% in online double conversion mode the 93PM is arguely best in class for improving data centre efficiency. With optional lithium ion batteries and models available in 30-500 kVA with an exceptionally small foot print, it should certainly be on your list to consider when choosing a UPS.

This Eaton 93PM UPS solution can offer up to 97 percent efficiency in double conversion mode and up to 99 percent when in energy saver mode.

The Centric 300 from Gammatronic represents the company’s latest advance in modern scalable UPS systems. It uses AC power and is one of the first in the world to incorporate a modular design as well as the convenience of touch screen technology. Users with greater power requirements can easily link up to five Centric units together to ensure a strong supply of consistent power. With an efficiency of upto 96.5% and a small light weight foot print, the Centric 300 is a great choice to consider when it comes to protecting Data Centre Loads.

Features of the Centric 300 include:

- Continuous operation during expansion and maintenance
- Hot swap modules
- Advanced LCD touch screen.
- True online technology.
- 96.5% efficiency.
- PF = 1
- Sleek 19’’ design
- Small footprint
- Lightweight

The Riello Multipower modular UPS systems offer expanded convenience and savings, load Range 75kVA to 294KVA.

Riello offers a UPS system that applies transformerless technology to achieve an efficiency rating of up to 96.5 percent. It applies high density power in a compact space, as well as a modular design that makes scalability much easier to accomplish when the need arises.

The Power Cabinets (PWC – 2 versions) and the Battery Cabinet. The Power Cabinets can accommodate either only the 25 kW Power Modules (PM25) or 42 kW Power Modules (PM42). The available UPS power and redundancy level can expand vertically using the PM25 power module from:

25 to 125 kW in one single Power Cabinet (PWC 130) 25 to 175 kW in one single Power Cabinet (PWC 300)

Multipower power solution can expand vertically using the PM42 power module from:

42 to 294 kW in one single Power (PWC 300)

In Addition, Up to four complete Power Cabinets can be connected in parallel, increasing the capacity including redundancy respectively from:

125 up to 500 kW (with PM25) 175 up to 700 kW (with PM25) 294 up to 1176 kW (with PM42)

What Lithium Batteries Can Offer.

One of the latest advances in UPS technology is the use of lithium batteries. Currently, their use remains very limited, but as manufacturing costs and research advances, we can expect usage levels to increase greatly over time.

Currently, lithium batteries cost much more to purchase than their traditional counterparts, as much as 50% to 200% more in some cases. As with all emerging technologies, expect costs to come down over time. Lithium batteries offer advantages that make up for the upfront cost, however. thanks to an incredible 10 year life span that dwarfs traditional options. They also have lower maintenance costs than other battery options.

Lithium batteries may be a new technology with limited applications in UPS systems, but they have thousands of current uses. Because lithium batteries do not use as many toxic substances in their manufacture as traditional batteries do, they have shown themselves to be a safe option time and time again.
