Requirement: Fail-safe energy supply for electrolysis plants

Electrolysis is a key technology für green hydrogen

Hydrogen production has become an important component of a future CO2-free energy supply for industry, transport and private households. In the course of this development a process has emerged as the key technology for energy transition: Electrolysis.

Hydrogen as an energy carrier
It is used to produce green hydrogen from renewable energies. In addition, electrical energy from wind and solar power plants can also be converted into hydrogen with the electrolysis process and stored in pressure tanks. When required (no wind, no sun), the hydrogen is fed back into the grid as electrical energy via fuel cells. The fuel cell also functions as an electric drive for vehicles, such as lorries and buses.

Solution: Fail-safe power supply with EA-Power Racks

Reliable hydrogen production in electrolysis plants

Demand for green hydrogen from electrolysis plants is growing rapidly. To ensure that the plants can continuously produce quantities of hydrogen, a fail-safe power supply is becoming increasingly important. The modular EA-Power Racks reliably secure this.

Modular EA-Power Racks Solution: Additional benefits

  • Fail-safe power supplys
    If one module fails, the others continue to provide sufficient power
  • Up to 1.92 MW output power
    Parallel-connected in EA-Power Rack
  • Communication and Ethernet interfaces
    For integration into the automation solution and for remote maintenance
  • True autoranging
    Larger voltage and current range in one unit
  • Air- or water-cooled versions
    For optimal adaptation to application requirements
  • Plug-and-play
    EA-Power Racks are prewired for safety and immediate use
  • Made in Germany

Modular EA-Power Racks Solution

Peace of mind from total system failure.

Fail-safe energy creation for electrolysis plants
In contrast to monolithic energy systems, the EA-Power Racks are modular in design and offer the greatest possible fail-safety. The advantage: If a module fails the power supply switches off for a short time. The rack automatically reconfigures itself and continues to supply modules to supply energy for the electrolysis.

Programmable DC-Power Supplies for EA-Power Racks

The power supplies of the EA-PS 10000 4U and EA-PSI 10000 4U series can be perfectly integrated into EA-Power Racks. Depending on the power rating, a 19“ EA-Power Rack with 42 height units can accommodate up to 8 units. The units are flexibly configured according to the application requirements, optionally as air-cooled or water-cooled units.

High power density. Air- or water-cooled.

Autoranging and high power density
The units can be connected in parallel in the EA-Power Rack up to an output power of 1.92 MW with a maximum operating voltage of up to 2000 VDC. In addition to high power density, the DC power supplies offer true autoranging and are equipped with a plug- and-play interface slot for retrofitting
digital interfaces. Via a TFT touch display, operation, set-up and programming are intuitive and simple.

EA-Power Racks: The Features

High utility value. Optimum application adaptation.

Each EA-Power Rack is optimally adapted to your voltage and current requirements.

Can be automated
The EA-Power Racks can be seamlessly integrated (PROFINet, Ethercat, CAN, etc.) into the automation solution of your electrolysis plant. Standardized connections ensure simple installation and quick commissioning.

Integrated Ethernet interfaces make it easy for you to access the EA-Power Racks for remote maintenance and diagnostics. With these data and status information, you always have your system under control.

The compact EA-Power Rack has low footprint requirements inside the plant.

EA-Power Racks come prewired for safely and fully tested.
