Power Ratings

(Voltages, Currents)

The available voltage range portfolio goes from models with 0...80 V DC up to models with 0...750 V DC.

Input currents up to 0...1020 A with only one unit are available.

The series offers various power classes amongst the single models which can be extended up to 460 kW in cabinets for a significantly higher total current.

All models are built in 19“ wide rack enclosures with 3U or 6U of height and 460 mm (18.1”) of depth, which makes them ideal for use in 19“ cabinets of various sizes, for example 42U, and for the design of systems with very high power.

It's furthermore possible to build cabinet systems with mixed equipment, i.e. electronic loads and power supplies, in order to achieve the source-sink principle with high power ratings.

Manual operation is done with a TFT touch panel, two rotary knobs and a pushbutton.

The large color display shows all relevant set values and actual values at a glance.

The whole setup is also done with the human-machine interface, as well the configuration of functions (square, triangle, sine) etc.

The display is multilingual (German, English, Russian, Chinese).

Share bus

(parallel connection and two-quadrants operation)

The so-called "Share Bus“ is an analog connection at the rear of the devices and is used to balance current across multiple similar units in parallel connection, such as with loads of this series and series EA-ELR 9000.

It can also be used to build a two-quadrants system in connection with power supplies of series EA-PSI 9000 or EA-PS 9000.

This system is dedicated for testing purposes using the source-sink principle.

The devices of the EA-EL 9000 B series are equipped with thermal derating in order to avoid overheating when operating in the maximum power range.

The lower the ambient temperature and the better the cooling, the higher the power that the load can take.

The nominal intake power before the derating starts is defined at 21°C ambient temperature.

For purposes of testing all kinds of batteries, such as for example constant current or constant resistance discharging, the devices offer a battery test mode.

This show extra values for elapsed testing time and consumed capacity (Ah).

All the data can be recorded directly to USB stick. For photovoltaics related tests there is another function included as standard: MPP tracking.

Four modes allow for simulation of the typical characteristics of solar inverters being connected to solar modules or panels.

The function is used to determine typical operation parameters, such as the so-called Maximum Power Point and the related values Uᴍᴘᴘ, Iᴍᴘᴘ and Pᴍᴘᴘ.

One of the modes even offers particular analysis with different irradiation values in form of a table with 100 points.

For remote control, there are by default two interface ports (1x analog, 1x USB) available on the rear of the devices, which can also be extended by optional, pluggable and retrofittable, digital interface modules (dedicated slot).

For the implementation into the LabView IDE we offer ready-to-use components (VIs) to be used with the interface types USB, RS232, GPIB and Ethernet.

Other IDEs and interfaces are supported by documentation about the communication protocol.

Windows users can profit from the free software “EA Power Control”.

It offers a feature called “Sequencing”, where the device is controlled through a semi-automatic table in CSV format.

This table represents a simple test procedure and can be created and edited in MS Excel or other CSV editors and then imported into the software tool.
