Astrodyne

What Astrodyne does

Astrodyne TDI, founded in 1963 and headquartered in Nashua, New Hampshire, is a privately held manufacturer of power conversion and electromagnetic interference (EMI) filtering products serving medical, semiconductor, military and aerospace, industrial, EV/renewable energy, and professional-grade consumer appliance markets. The company's core technology stack spans AC/DC and DC/DC power supplies in open-frame, enclosed, encapsulated, board-mount, rack-mount, external-adapter, and ruggedized/hazloc form factors, complemented by a broad EMI/EMC filter portfolio (single-phase, IEC inlet, three-phase delta and WYE, feed-thru, MIL-COTS, Tempest, and MRI shielded-room variants), uninterruptible power supplies, power distribution units, toroidal transformers, programmable electronic loads, and a multi-coolant architecture covering liquid, forced-air, conduction, and convection solutions. Its flagship LiquaBlade platform delivers 16.5kW in a 1U liquid-cooled form factor with full programmability and scalable architecture targeted at semiconductor fab equipment, defense systems, and demanding industrial applications.

The business operates a sales-led, engineer-to-engineer model in which customers can engage via direct sales representatives, authorized distributors, an owned e-commerce storefront, or a quote-based inside sales motion for custom and high-volume enterprise programs. Pricing is quote-based across all product lines, with multi-year contract cadence implied for custom and MIL-spec work. The company monetizes primarily through hardware sales of catalog products plus custom design and modification services, and it bundles EMI pre-compliance testing as an add-on offering to support customer certification cycles. Operating geographies are global, with the firm identified as a key player in the global AC line filter market alongside Schaffner, TE Connectivity, TDK, and Murata.

Ownership and capital structure show a 2008 investment by Audax Private Equity and two bolt-on acquisitions (Jerome Industries in 2011 and TDI Power in 2014), indicating an active but undisclosed inorganic growth program under PE sponsorship. Leadership comprises CEO Christopher Viola, Chairman Mark Petty, and VP & GM of Power and Controls Joseph Deluca. Certifications include MIL-STD compliance for defense and aerospace products, and revenue is not publicly disclosed.
