The Intepro EL 9000 B is a high performance DC electronic load chassis and with a total of 15 different models to choose from, Intepro has a solution to fit any test requirement. 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 510 A within a single chassis are also available The load features six modes of operation and can be paralleled with multiple chassis for up to 72kW. The relation between power consumption and height of the devices is one of the best in the industry. With only 3U height for all models, the capability of consuming DC power of up to 7.2 kW per unit is impressive.

Key Features of the EL 9000 B: Programmable DC Load products:

  • Input Power Ratings

    1.2-7.2 kW; Expandable in cabinets up to 72 kW
  • Input Voltages

    0-80 V up to 0-750 V
  • User Profiles

    True function generator
  • Operation modes

    CV, CC, CP, CR
  • DC Load Sensors

    Remote sensing
  • Interfaces

    Galvanically isolated interfaces (analog and USB)
  • Connection

    Master-slave bus for parallel connection
  • Cooling

    Optional water cooled units available
  • Input currents

    Up to 510 A per unit

All models support the four common regulation modes of constant voltage (CV), constant current (CC), constant power (CP) and constant resistance (CR). The FPGA based control circuit provides valuable testing features, such as a function generator with a table based function for the simulation of nonlinear internal resistances.

For remote control, there are by default two interface ports (1x analog, 1x USB) available on the rear of the chassis, which can also be extended by optional, pluggable and retrofittable, digital interface modules (dedicated slot). Alternatively to the interface modules slot, all models can be equipped with a three-way interface (option 3W), which then offers 1x GPIB/IEEE, 1x USB and 1x Analog on the rear side of the chassis. For the implementation of the LabView IDE Intepro offers 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.

The models of the 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 continuous intake power after derating is stable up to 50°C ambient temperature.

A special feature of the EL 9000 B DC Electronic Load is the familiar, FPGA based, digital function and arbitrary wave form generator. It enables controlling and running user-customizable load profiles and can generate sine, square, saw tooth and ramp functions in arbitrary order. With a freely programmable digital value table of 3276 effective points, which is embedded in the control circuit, the devices can reproduce non-linear internal resistances, such as those of batteries or LED chains.

 

User Control

The large LCD touch panel offers a modern and intuitive user interface for controlling the four operating modes, Constant Voltage (CV), Constant Current (CC), Constant Power (CP) and Constant Resistance (CR). Response times for the control via analog or digital interfaces by the DSP controlled hardware are among the fastest in the industry. In parallel operation of multiple devices, a master-slave bus is used to connect the chassis to a create high power system where the actual values are totaled and the set values distributed.

Complex Sequence Generator

By linking together a number of differently configured sequences, complex progressions can be created. Smart configuration of the arbitrary generator can be used to match triangular, sine, rectangular or trapezoidal wave functions and thus, e.g. a sequence of rectangular waves with differing amplitudes or duty cycles can be produced.

For the implementation of the LabView IDE Intepro offers ready-to-use components (VIs) to be used with the Ethernet interface. Other IDEs and interfaces are supported by documentation within the communication protocol.

Avoid Overheating Failures

The models of the 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 dc electronic load can take. The continuous intake power after derating is stable up to 50°C ambient temperature.
