About Energy Technologies, Inc.
Energy Technologies, Inc. (ETI) is a privately held US electronics and technology manufacturer established in 1991 and headquartered at 219 Park Avenue East in Mansfield, Ohio (ETI — About). ETI specializes in the design and manufacture of rugged, high-reliability AC and DC power products for critical applications in both normal and hostile environments — defense, government, industrial, medical, and telecommunications sectors (ETI on LinkedIn).
ETI’s product lines are structured around three trade-marked platforms — Rugged Power™, Military Power®, and Tactical Power® — that together cover the production, conditioning, storage, and control of AC and DC power for shelters, vehicles, shipboard, submarine, aircraft, and field-deployed applications, as well as stationary use in factories, utilities, networks, offshore platforms, and pipelines (RuggedSystems.com — ETI product overview). Their offerings have been utilized in tens of thousands of installations worldwide.
ETI power products are modular in design, available in a variety of sizes, and may be modified to suit a particular application or integrated into a complete system solution. Units are designed to prevent damage due to mechanical shock and vibration and are built rugged for hostile-environment operation (MilitaryPower.com / etisite.com).

Sourcing legacy or discontinued ETI parts
Because ETI product lines are largely custom-configured to end-customer specifications, replacement units and spares often carry non-catalog part numbers, revision suffixes, and program-specific nameplates (e.g. Army CECOM, Navy SPAWAR, USAF, Marine Corps, or prime-contractor drawing numbers). If you have an ETI unit in service and cannot get a factory quote — or need a discontinued model for a depot repair — send us the full nameplate data (model, serial, program number, and any drawing revisions) and we’ll check our own inventory and our sourcing network for exact-match or form-fit-function replacements.
