The EA Elektro-Automatik Group is Europe’s leading supplier in the area of power electronics for R & D and industrial application. At the headquarter in Germany. EA develops, research and manufacture on an area of 19,000 m2 at our headquarters in Germany and research, develop and manufacture leading-edge laboratory power supplies with a wide application spectrum. EA Elektro-Automatik equipment are used in various industries, such as:
As a globally active company EA maintains close contact with national and international customers and partners. The sales network includes branches in China and USA, sales office in Spain and an extensive partner network.
The programmable DC power supply family from EA range in power from 80W benchtop devices up to 30kW in a single chassis. High power density units can be easily paralleled up to 1,92MW in output, with up to 2000 VDC. All EA Elektro-Automatik DC programmable power supplies feature true Autoranging which automatically offers increased current at lower voltages, enabling a single supply to meet wider test requirements.
The PS and PSI series feature 5 “TFT touch panel display for intuitive control, setup and programming. The intelligent interface allows you to program and test quickly without the need for extensive manual review. This user-friendly touchscreen is a feature not found on competing benchtop supplies.
Most of the PS / I family of programmable dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface control and built-in test routines for battery test, photovoltaic simulation and MPP tracking, to name a few.
All EA power supplies provide true autoranging giving full power across a larger operating range to test more devices with just one supply. Autoranging enables the power supply to automatically adapt to higher output voltages when there is a smaller current or handle higher currents when there is a lower voltage. EA’s true autoranging can deliver full power down to 33% of rated output voltage.
A common requirement for dc power supplies is to deliver the output voltage or current with a waveform other than a straight-line dc signal. EA’s built-in function generator includes options for sine, triangle, square, and trapezoidal waveforms, as well as custom arbitrary waveforms. In addition, the solution offers configuration tools for ramps, UI and IU tables and simulations for fuel cells and photovoltaics.
EA “Anybus” modules are easily installed by the user and can be swapped out with just a few minutes and a screwdriver when different communication protocols are desired. For computer or remote control, you have many choices, such as Ethernet, USB, EtherCAT, ProfiNET, ProfiBUS, CAN, CANOpen, Modbus, Devicenet and RS232 interfaces.

Select devices and integrate into the rack
New high-performance systems are constantly being developed for the electrification of the world. Associated with this is the testing requirement for the battery packs, fuel cell stacks, solar systems or electrolysis systems (or: electrolysers). With the modular EA rack system you have the possibility to select the suitable devices for your tests and simulations and to integrate them into the modular EA rack system
Power supplies and loads
Configure 3U, 4U and 6U devices into 42U, 38U, 24U and 15U rack systems. Combine EA-10000 and EA-10000 Industrial series programmable power supplies, bidirectional power supplies, or regenerative loads. System performance can be increased by connecting devices in parallel. In a 42U rack with 5 units of 60 kW you can reach 300 kW, for the maximum power of 3.84 MW you can connect up to 64 units in 13 racks.
