Overview

Eltek is a Norwegian power-electronics brand whose products are used to convert, regulate, distribute, and protect electrical power in telecommunications and other infrastructure-heavy applications. The business originated in 1971 in Drammen, Norway, initially producing electronic equipment for military use before expanding into broader industrial and commercial power-supply markets. During the 1990s, Eltek increasingly concentrated on the telecommunications sector, where dependable direct-current power systems became essential for network equipment and distributed communications infrastructure. The brand has been associated particularly with rectifiers, power systems, inverters, and related conversion equipment. Its technology is used in environments where electrical continuity, efficiency, remote supervision, and compact installation are important, including telecom networks, data centers, power utilities, transportation systems, and industrial facilities. Eltek products have been marketed internationally, with the brand reported as serving customers in more than 100 countries. The wider organization has also maintained offices in numerous countries, reflecting the global nature of its customer base and channel network. Eltek became a publicly traded Norwegian company in 1998 under the name Eltek ASA. In 2007, it acquired Texas-based Valere Power, a transaction that broadened its power-conversion portfolio and led to the name Eltek Valere AS. The company subsequently adopted the name Eltek AS in 2011. In 2015, Delta Electronics acquired Eltek ASA. Following the acquisition, Eltek was removed from the Oslo Stock Exchange and became part of Delta's global power and energy-management activities. The operating company in Norway later changed its legal name to Delta Electronics (Norway) AS in 2023. Eltek nevertheless continued as a commercial brand, with product development and sales conducted within the Delta Electronics organization. Drammen remains associated with the brand's Norwegian base and historical origins. Eltek's current identity is therefore best understood as a specialized infrastructure-technology brand rather than an independent listed corporation. Its market proposition centers on reliable and efficient power conversion for mission-critical systems, especially where downtime can affect communications, computing, transportation, or utility operations.

History

Eltek was established in Drammen, Norway, in 1971. Its early activities centered on electronic equipment for military applications. The company later broadened its scope into power supplies and associated electronic systems for industrial and commercial customers. This transition placed Eltek in a market where dependable conversion and control of electrical power were increasingly important across communications, infrastructure, and industrial operations. During the 1990s, Eltek shifted significant strategic attention toward telecommunications. The expansion of fixed and mobile communications networks created demand for compact, efficient, and highly dependable power systems capable of supporting network equipment continuously. Eltek's product portfolio developed around this requirement, including rectifiers, power systems, inverters, and related infrastructure products. Telecommunications became a central area of activity, although the company also served data centers, utilities, transportation, and other industrial users. Eltek was listed on the Oslo Stock Exchange in 1998 as Eltek ASA. Public-company status supported the expansion of an internationally oriented business whose products were sold through a broad geographic network. In 2007, Eltek acquired Valere Power, a Texas-based power-conversion company. The acquisition expanded Eltek's presence and capabilities in power systems and was followed by the adoption of the name Eltek Valere AS. In 2011, the company changed its name again to Eltek AS. The company became part of Delta Electronics in 2015, when Delta acquired Eltek ASA. The transaction ended Eltek's status as an independent Oslo-listed company and integrated its activities into Delta's broader portfolio of power and energy-management technologies. Eltek remained recognizable in the market through its established product brand, technology portfolio, and customer relationships. By 2018, Eltek was reported to have approximately 2,000 employees and offices in about 40 countries. Its products were available in more than 100 countries and served a range of infrastructure sectors, with telecommunications remaining an important application area. In 2023, the Norwegian legal entity changed its name to Delta Electronics (Norway) AS. The change reflected the company's ownership and organizational integration, while the Eltek name continued to be used for products and market offerings. The business remains based in Drammen, the location associated with Eltek's origins and Norwegian operations.
