Making a Leap with Power Quality Meters - Electrical Equipment Brand DEESYS

Last spring many people in Korea had a hard time because of severe smog, yellow dust and pollen. But humans are the not the only victims of the deteriorating air quality. Internet Data Centers, which operate and manage corporate servers, are particularly sensitive to fine dust and poor air quality.

DEESYS (www.deesys.com), which specializes in manufacturing electrical equipment, develops power quality meters and environmental surveillance sensors for places like Internet Data Centers. We met with its CEO, Lee Bo-in, who dreams of a comprehensive electrical equipment brand.

Founded in 1979, DEESYS has been dedicated solely to the manufacturing of protection relays, such as Earth Leakage Detectors, ground fault relays, motor protection relays and zero phase current transformers. Marking its 38th anniversary this year, DEESYS manufactures highly functional products through its many years of recognition and relentless development. What's more is, it has secured price competitiveness by using its own technologies. As a result, it was able to beat some 20 rivals in the domestic electrical equipment market to occupy the largest market share in the Earth Leakage Detector sector.

DEESYS has been at the forefront of digitalizing analog relays in the relatively narrow electrical equipment market by developing state-of-the-art digital relays using its expertise in the manufacturing of analog relays. CEO Lee says "Analog relays are still in wide use, but they are gradually being replaced by digital products." DEESYS's digital relays are even exported to Japan, a leader in the global relay market.

DEESYS has been diversifying its products through power quality meters and environmental surveillance sensors. Existing circuit development methods and electrical theories, etc, were significantly applied to the development of power quality meters and environmental surveillance sensors. Power quality meters maintain quality by reacting sensitively even to slight changes in voltage and recording electric power change. This helps to prevent serious damage from voltage changes. Recently, the company signed a deal with KT's Internet Data Center. “There are about 600 Internet data centers in Korea. We will target them pro-actively to supply our power quality meters," says CEO Lee.

DEESYS has also developed environmental surveillance sensors to maintain the high quality of internet servers, which are sensitive to fine dust, humidity and temperature. DEESYS is the only company in Korea which power quality meters and environmental sensors are manufactured together to ensure data compatibility. Currently, the company is developing an app using IoT technology to monitor the situation in server rooms in real time. “Our environmental sensors will likely be used in various places, as environmental issues such as smog have become very serious lately. We plan to expand our presence in overseas markets as well, such as Indonesia,” states CEO Lee.
