Modular Regen Loads up to 3000V

Do you regularly need to test power sources with high dynamics? Perhaps you need a versatile DC electronic load to cover all your research requirements? Our new generation of modular power recycling loads offer the perfect solution.

18kW G5-REGEN ModuleThe G5-REGEN builds on the technical features of the widely adopted ELP-GXS platform. Over 40 years of development have been invested to ensure the new DC electronic load is the most advanced on the market. Each module provides the ability to sink DC power up to high voltage and currents, ideal for testing energy storage devices.

Among the new features is the ability to implement a programmable ripple, allowing an AC ripple on a DC battery link to be recreated. By utilising the embedded function generator the user can set a current ripple at up to 10kHz. The magnitude can be up to 5% of the nominal system current. Depending on the impedance of the DUT the resulting voltage ripple can be calculated.

Generation 5: New Features162kW G5-REGEN Cabinet

  • Sink voltages up to 3000V
  • Two current ranges for higher accuracy
  • Programmable voltage and current ripple
  • Ultra-fast dynamic behaviour
  • Mixed power nominals in master-slave

A current step between 0% to 90% sinking current can be as quick as 50μs. Switchable output capacitance is also provided to improve stability when operating in constant voltage mode. This is particularly useful to assist the fast current demands when testing high speed electric drives, as some DUTs will be damaged if the voltage drops too low.

Modules can be arranged in series, parallel or matrix configurations. Outputs up to 3000V are now possible into the megawatt range. Another improvement is the ability to connect units in master/slave with different nominal values. For example, an 18kW/500V/108A module will connect in parallel with a 54kW/500V/324A unit to provide 72kW/500V/432A.

Each unit has an extensive feature set which includes programmable PID parameters and an inbuilt 8 channel recording scope. Adjustable power and resistance limits are provided, as well as a selection of remote control options including high-speed CAN. An intuitive operating GUI is standard which provides a variety of programming features and second level parameters, useful for optimising test processes.
