About Astrodyne TDI

Astrodyne TDI is a global designer and manufacturer of highly engineered power solutions for demanding applications. The company's history is one of strategic growth through acquisitions. Astrodyne was founded in 1994, and in 2014, it acquired TDI Power, a company established over 50 years prior with expertise in high-power applications. This merger created a comprehensive provider of power solutions, combining Astrodyne's low-to-medium power products and EMI filters with TDI's high-power capabilities. Subsequent acquisitions included the EMI filter lines from Radius Power, LCR Electronics, and Filter Concepts, and, more recently, Powertronix in 2023, which added toroidal transformers and power distribution equipment to its portfolio. In November 2017, the company was acquired by Tinicum L.P., a private investment partnership. The company's business model is centered on a collaborative, engineer-to-engineer approach to develop custom and standard power solutions for original equipment manufacturers (OEMs). Astrodyne TDI serves a diverse range of high-stakes markets, including semiconductor capital equipment, medical, aerospace, defense, and industrial automation. Its clients are companies that require precise and reliable power conversion in harsh or highly variable conditions. The firm operates globally with engineering and manufacturing centers in the United States and China, and a presence in Europe and Malaysia, allowing it to provide localized support with a global reach. Astrodyne TDI's product portfolio is extensive, featuring AC/DC power supplies, DC/DC converters, EMI/RFI filters, power distribution units (PDUs), and transformers. Its products are designed for critical applications such as life-saving heart-assist devices, semiconductor manufacturing equipment, military aircraft, radar systems, and industrial control systems. The company provides solutions with various cooling methods, including liquid-cooled, forced air, and conduction, to meet specific environmental and operational demands. A key differentiator is its ability to create fully customized, turnkey solutions that integrate power supplies with features like RF filtering, digital communication, and variable output, helping clients reduce costs and time to market.
