The EA solutions are ideal for applications in e-Mobility and Automotive, Energy Storage, Telecommunications, Aerospace, Alternative Energies, and many emerging markets such as fuel cell and hydrogen electrolysis.

EA product line solutions demonstrate expertise to address new applications such as battery module and pack development and quality assurance testing, battery module and pack emulation, electrolysis research, and fuel cell testing and emulation.

With the combination of Tektronix’s leading oscilloscopes, analyzers, and signal sources, combined with the Keithley line of precision instruments, and the EA line of high-power technology, customers can now enjoy precise, flexible, and efficient solutions from Tektronix for all their power engineering needs.

True Autoranging – Advantages for Test

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.

Save budget and space
No oversizing supply
One supply tests more
Versatile for future tests

Waveform Function Generator

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.

Features

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.
