For Data Center

Data centers are confronting severe energy challenges as power demand surges. Projections indicate that their annual electricity consumption will soon match that of Japan and could account for 4% of global power generation by 2030.

Data centers are confronting severe energy challenges as power demand surges. Projections indicate that their annual electricity consumption will soon match that of Japan and could account for 4% of global power generation by 2030. This rapid expansion is placing considerable strain on grid systems, which are struggling to keep up. Meanwhile, data centers must compete with other industries for limited power resources, all under growing pressure to meet environmental compliance standards. How can we effectively tackle the energy dilemma facing data centers?

High Reliability Requirements

The load class (grade) in data centers is mostly above Level 1, demanding extremely high power supply reliability.

High Efficiency Requirements

Should meet or exceed Class 1 energy efficiency standards.

Strong Overload Capacity

Able to handle sudden load increases.

High Fire Safety Requirements

Ensure the safe operation of the data center.

High Voltage Transformer for Data Center

Our approach to tackle data center challenges

At Pearl Electric, we understand the unique requirements of data centers and have extensive experience producing transformers for data centers.

Load Capacity and Load Rate

The load of large data centers typically increases with business development. The optimal load rate (actual load / rated capacity) for a transformer is 70%-85%, which is the industry-recognized "golden range."

Voltage Stability and Harmonic Suppression

For data centers, equipment such as servers and UPS are sensitive to harmonics (excessive harmonics can cause equipment malfunctions). It is necessary to choose transformers with low harmonic distortion rate (≤3%) and harmonic suppression function.

Rich Experience in Transformer Production

Pearl Electric established in 1958, located in Guangzhou, China which is an experienced transformer factory to design, produce and supply distribution transformer and power transformer.

FAQs on data center power transformer

How much power do data centers use?

Data centers consume a significant amount of power, and their energy usage can vary widely based on several factors, including size, design, efficiency, and the type of equipment used. Small data centers may use 1-5 MW, while larger ones can consume 20MW to over 100MW-2000MW.

What is the power supply of a data center?

Data center power supplies typically come from the local electrical grid which provides the primary source of power. To ensure continuous operation during power outages, data centers often have backup generators (usually diesel or natural gas) that can provide power until utility service is restored. In locations where the grid is unavailable or unable to supply sufficient power, data center also have onsite power generation to deliver continuous power to the data center.

Can data center use renewable energy?

Yes, some data centers are incorporating renewable energy sources, such as solar, wind and hydro power, to power their operations and reduce their carbon footprint.
