EA Elektro-Automatik

EA Elektro-Automatik

EA Elektro-Automatik is a German manufacturer of high-performance programmable DC power supplies and electronic loads. Founded in Viersen, Germany, the company specializes in precision power test equipment designed for research and development, production testing, and industrial applications. EA's product portfolio covers a wide power range, from compact bench-top units to rack-mounted high-power systems exceeding 30 kW.

The company is particularly recognized for its regenerative electronic loads — systems capable of feeding energy back into the power grid rather than dissipating it as heat — making them an energy-efficient choice for large-scale battery testing and power electronics development. EA power supplies are widely integrated into automated test environments using SCPI commands over USB, LAN, and analog interfaces.

Key Product Lines

• Programmable DC Power Supplies (EA-PS series) — single and multi-output laboratory and industrial power supplies with digital interfaces for manual and automated operation
• DC Electronic Loads (EA-EL series) — programmable loads for battery characterization, DC-DC converter testing, and power supply verification across a wide current and voltage range
• Regenerative Electronic Loads — energy-recuperating loads that return power to the grid, designed for high-power EV battery and fuel cell testing
• Bidirectional Power Supplies — units that operate as both source and sink, ideal for battery simulation and grid-tied test automation

Industries Served

EA Elektro-Automatik equipment is used in automotive and electric vehicle development, aerospace and defense testing, renewable energy (solar inverters, fuel cells), power electronics R&D, semiconductor manufacturing, and production line testing. Their systems are a common choice for laboratories requiring high-power, high-accuracy DC sources with full automation capability.
