Elektro-Automatik

Elektro-Automatik

Elektro-Automatik (EA) is a German manufacturer of programmable power supplies, electronic loads, and battery test systems. Founded in Viersen, Germany, the company develops high-performance DC power supplies and bidirectional power converters used in research, development, and automated production test environments worldwide. EA is recognized for its PSI and PS series of programmable power supplies offering high output resolution, wide voltage and current ranges, and robust digital communication interfaces.

A key differentiator of EA's product line is the integration of regenerative (bidirectional) technology in both power supplies and electronic loads, allowing excess energy to be returned to the AC grid rather than dissipated as heat. This approach reduces operating costs in high-power test environments and is particularly relevant for EV battery and energy storage testing applications.

Key Product Lines

• Programmable DC power supplies — PSI and PS series covering laboratory benchtop to high-power rack-mount configurations with GPIB, USB, and Ethernet interfaces
• Electronic loads — resistive, constant current, constant voltage, and constant power modes for testing power conversion equipment and DC sources
• Battery test systems — BCTS and BT series cyclers and analyzers for charge/discharge characterization of lithium-ion, lead-acid, and emerging battery chemistries
• Bidirectional power supplies — regenerative units for energy-efficient testing of motors, inverters, fuel cells, and energy storage devices
• Turn-key test cabinets — integrated system solutions for high-power production and validation testing

Industries Served

Elektro-Automatik equipment is used in automotive and electric vehicle battery development, renewable energy and grid storage, aerospace & defense, consumer electronics manufacturing, power electronics R&D, and academic laboratories. Their battery cyclers and regenerative loads are particularly valued for EV battery cell and pack testing, where energy recovery during cycling significantly reduces test infrastructure operating costs.
