What EA Elektro-Automatik does

EA Elektro-Automatik is a Germany-based specialist, founded in 1974 and headquartered in Viersen, that designs and manufactures high-performance programmable DC power supplies, bidirectional power supplies, regenerative electronic loads, and battery test and impedance measurement systems. Its core technology stack centers on regenerative bidirectional architectures that achieve 96% energy efficiency by returning energy to the grid rather than dissipating it as heat, paired with multi-channel battery cyclers offering 1ms communication speeds and broad-frequency EIS impedance measurement accurate to better than 1%. The product catalog spans bench units, high-power DC racks, industrial power units, battery impedance meters, and accessories such as serial connection boxes, sold under product lines including the EA-PSB, EA-BTS, EA-BT, EA-BIM, EA-EL/ELR, and EA-PS/PSI series.

The company operates as a division of Tektronix, which is itself owned by Ralliant Corporation following Ralliant's 2023 acquisition of Fortive's Test & Measurement segment and Fortive's January 2024 acquisition of EA Elektro-Automatik (EA) Holding GmbH for $1.45 billion. EA sells globally through Tektronix's direct enterprise sales force, a VAR channel that includes partners such as PPST Solutions, and Tektronix's multi-language online store, targeting verticals including e-mobility and automotive, energy storage, AI data centers, aerospace and defense, renewable energy, telecommunications, and emerging fuel cell and hydrogen applications. Revenue is generated primarily through hardware sales of test and measurement equipment supplemented by factory service, calibration, repair, and managed services, with quote-based enterprise pricing and multi-year service contracts. Ralliant recorded a $1.4 billion non-cash goodwill impairment in its Test & Measurement segment tied to the EA acquisition in 2026, reflecting reduced long-term forecasts for electric vehicle adoption.
