High power density

EA’s programmable power supplies, connected in parallel in the EA Power Racks, are ideal for safeguarding hydrogen production.

Electrolyser stacks

Precise tests of degradation behavior and efficiency

Dynamic tests provide valuable information about the behaviour of electrolyser stacks with different power supply qualities. EA offers the ideal power electronics for these tests – with fully controllable devices, high accuracy of the values determined and maximum flexibility when setting the parameters.

EA highlight: DC ripple in the integrated function generator

The superposition of a direct current with an alternating current can be set using the function generator.

Next level testing with EA

• Fully controllable and adjustable EA power electronics
  (OV – nominal voltage, 0A – nominal current, 0W – nominal power)
• Precise regulation of the desired voltage, current and power values
• Function generator: Investigation of the effects of DC
