Milestones
During the half-century journey, Delta has experienced one important moment after another. Let's take a look at our history!

1971

Founded at on Min-An Road, Sinjhuang, Taipei County, Taiwan, Delta Electronics produced TV coils and electronic components.

Mr. Bruce Cheng raised NT$300,000 to establish Delta Electronics in a small factory on Min-An Road, Sinjhuang, Taipei County, near the edge of rice fields. The number of employees in the beginning was only 15. Delta produced TV parts, and the main products were TV coils and intermediate frequency transformers (IFT).

1975

Registered as Delta Electronics, Inc.

1980

Set up a US office.

The first step of Delta's globalization was to establish an office in the US. In addition to serving US customers, Delta could communicate with the head offices of companies in the US directly without having to receive orders through an international procurement office.

1981

Started mass production of EMI filters to enter the personal computer market.

With the emergence of the personal computer market in the 1980s, Delta entered this field to respond to this trend. The first product for the computer market was EMI filters, making Delta the first EMI filter manufacturer in Taiwan. With the advantages of quality and price, Delta won the favor of customers and is still the main supplier of EMI filters today.

1983

Started mass production of switching power supplies.

Power supplies were the key to Delta's substantial growth in the 1980s.
In the 1980s, most transformers were made of traditional silicon steel sheets, the products were thus heavy and large, with an efficiency of only 50% or even lower. The switching power supplies developed by Delta were not only lightweight but also thin and compact, with a superior efficiency of at least 60% or more at the time.
To enhance product quality, Delta began producing switching power supplies with a surface-mount design in 1985 as the first such manufacturer in the world.
Delta has continued to improve the energy conversion efficiency of its power products. Today, the efficiency of Delta’s products all exceed 90%. In particular, the industry-leading efficiency of Delta’s telecom power products exceeds 98% and the efficiency of its solar inverters is as high as 99.2%.

1988

Started mass production of DC brushless fans.

DC brushless fans are products for computer heat dissipation. Due to a huge increase in power supply orders, fans purchased externally were often in short supply, so Delta decided to develop its own fans. Delta continued to improve its designs and manufacturing process, while also developing automated solutions. Delta later made a major breakthrough in technology that significantly enhanced its competitiveness. In 2006, Delta ranked first in the global market for DC brushless fans.

Listed on the Taiwan Stock Exchange; stock code: 2308.

Delta began to produce switching power supplies in 1983, and its revenue in the year increased by 87.5% compared to 1982. During the five years from 1983 through 1988, Delta's revenue increased nine-fold, breaking the US$100 million mark in 1988. It was then listed on the Taiwan Stock Exchange as the eighth publicly listed company in the electronics industry (stock code: 2308).

Invested in the establishment of Delta Electronics (Thailand) Public Company Limited (DET).

Founded in 1988, DET initially focused on the design and manufacturing of power supply and thermal management products. DET was listed on the Stock Exchange of Thailand (SET) in 1995 and has now become the largest supplier of electronic products listed on the SET. In 2019, DEISG, a subsidiary of Delta, acquired 42.85% of the equity of DET through a public tender offer.
