EA-EL 9500-450 B 24U GH Electronic Load

This series EA-EL 9000 B 15U and EA-EL 9000 B 24U extend the electronic load series EA-EL 9000 B 3U with high power models in mobile 19” cabinets. There is a choice of 20 different configurations with vari-ous power ratings. A cabinet system is considered as a single electronic load device with extended power, with manual handling and remote control being usual, while offering the same features like the standard models of EA-EL 9000 B 3U series.
There are two cabinet sizes with 15U or 24U, which are equipped with 3 to 6 load units, depending on the model. Some models even offer to further extend the available power by adding another load unit through retrofitting. The cabinets also feature lockable rear and front doors, as well as four casters which can be fixed. The system will be shipped completely configured and will be ready to use right after installation on location.

  • Function generator
  • USB and analog interface built in
  • Slot for optional interface modules Profinet, Profibus, CAN, CANopen, Ethernet, EtherCAT, Mod-Bus TCP
  • SCPI and ModBus RTU/TCP command set
  • LabView VIs and remote control software (Windows)
  • Color TFT touch panel

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...3060 A with only one cabinet are available. The series offers various power classes with 10.8 kW up to 27 kW steady power and 10.8 kW up to 43.2 kW peak power.

Display and control panel

Set values and actual values of output voltage, output current and output power are clearly represented on the graphic display. The color TFT screen is touch sensitive and can be intuitively used to control all func-tions of the device with just a finger tip.
Set values of voltage, current, power or resistance can be adjusted using the rotary knobs or entered direct-ly via a numeric pad. To prevent unintentional operations, all operation controls can be locked.

Function generator

All models of this series include a software based function generator which can generate typical functions, as displayed in the figure below, and apply them to either the input voltage or the input current. The gener-ator can be completely configured and controlled by using the touch panel on the front of the device, or by remote control via one of the digital interfaces.
The predefined functions offer all necessary parameters to the user, such as Y offset, time / frequency or amplitude, for full configuration ability.

Remote control & connectivity

Monitoring, control and configuration of these load devices can either be done using the built-in USB inter-face or via one of various optional digital interfaces (see page 144). There is furthermore a standard ana-log interface for control and monitoring. All interfaces are galvanically isolated from the DC input.
For the implementation into the LabView IDE we offer ready-to-use components (VIs) to be used with the interface types USB, RS23 and Ethernet. Other IDEs and interfaces are supported by documentation about the communication protocol.

Windows users can profit from the free software “EA Pow-er Control”. It offers a feature called “Sequencing”, where the device is controlled through a table in CSV format to achieve automatic test runs. This table represents simple to complex test procedure and can be created and edited in MS Excel or other CSV editors and then imported into the software tool. This software also allows for the control of up to 20 units at once with an optional feature called “Multi Control” (licensed, not free of charge). See page 146 for more information.
