Technical FAQ
Industrial Power Engineering Questions
Expert insights from Astrodyne TDI’s senior application engineering group.
Astrodyne TDI manufactures low-power supplies from 5W to 1000W in open-frame, enclosed, encapsulated, board-mount, and adapter configurations. For large-scale industrial machinery, semiconductor tools, and dynamic load testing, we offer high-power platforms spanning 1 kW to 500 kW with output voltages up to 2.5 kV DC.
Industrial environments generate significant common-mode and differential-mode noise from variable frequency drives, switching supplies, and high-frequency welding. Our EMI/EMC filters (rated 1A to 2500A, up to 600 VAC/1200 VDC) attenuate conducted emissions between 9 kHz and 30 MHz, allowing OEMs to achieve compliance with FCC, CISPR, and European EMC Directives.
Yes. While we maintain an extensive catalog of off-the-shelf standard products, a substantial portion of our industrial business involves modified standard or full custom designs. Our in-house engineering team designs custom mechanical enclosures, specialized potting, custom magnetic components, and tailored firmware to meet exact OEM specifications.
Our manufacturing sites operate under ISO 9001:2015 and ISO 13485 certified quality management systems. Products are designed and qualified to meet international safety and performance standards, including UL/cUL, CE, SEMI F47 for voltage sag immunity, Energy Star Level VI efficiency, Factory Mutual (FM), and Hazardous Location (HazLoc) Class I Division 2 requirements.
