Power Conversion Capabilities

Design, manufacturing, test, and lifecycle support of mission critical power conversion

Various military and critical applications each present different demands at the equipment power interface. Abbott Technologies designs, manufactures, tests, and sustains the hardware that converts platform power into the clean, quiet, regulated DC that a mission depends on. With in house design and manufacturing capability, we can provide catalog and modified-standard products, designs engineered to your specification or source-control drawing, and build-to-print manufacturing. We can also provide replacements for units no longer supported by other manufacturers.

Abbott Technologies has served many programs in the aerospace, defense, transportation, and communication industries since 1961. Customers include departments of the U.S Government, armed forces, and major prime and sub-contractors.

Engineering

Abbott Technologies designs are engineered down to the component: circuit, transformers and inductors, board, and enclosure, under the formal design controls of our AS9100D system. This not only allows for modifications with significantly reduced risk and cost, but also to control size, weight, and power directly, and keep a design supportable decades into a program. Behind the team sits a working library built order by order since 1961, so most new requirements can begin from a proven baseline. Tools include 3D solid modeling, computer-aided engineering, circuit design and PCB layout, and simulation.

Manufacturing

Production runs on an integrated ERP system capable of high and low volumes. Assembly to IPC-A-610 and J-STD-001, conformal coating and staking in house, ESD and FOD discipline at every bench, and 100% inspection.

Test

In house EMI and ESS capabilities conforming to most requirements of MIL-STD-461, MIL-STD-810, and DO-160, acceptance testing on calibrated equipment, and evidence packages matched to your review. Certifications and practices: Quality Assurance.

Sustainment and Obsolescence

Most power electronics manufacturers obsolete products on commercial timelines; platforms serve for decades. Abbott Technologies designs stay buildable under full configuration control to the component level with GIDEP-informed parts surveillance, and when another manufacturers’ units becomes unsupportable, we replace it.
