Software Tool for ACL Series Loads Available

Tool View 3 Phase

For the AC-DC electronic loads of the ACL series, the associated control software, the ACL Tool, is now available with among others the following functions.

In addition to the “Channel Coupling” setting, which is useful for three-phase applications, the load inputs of the existing channels are controlled centrally from each function view.

In the main window the most important device settings are made. These are, in addition to the basic operating mode of the control with associated setting value, the peak value of the current limitation, AC or DC mode and the data acquisition.

Data Acquisition

There are two different types of data acquisition: a high-resolution one, whose measurement data is stored internally in the load, and a low-resolution one for long measurements, which is controlled by the software tool and which saves the data to a CSV file on the PC.

Waveforms

The AC waveform of the load current and its synchronization source can be configured. The waveforms can be created, edited, exported and imported in the ACL tool. All waveforms can be modified by crest factor, phase cut and phase shift (phase shift only possible in combination with crest factor or phase cut).

  • Sinusoidal waveform
  • Harmonic waveform
    A harmonic waveform can be configured by entering the percentages of even and odd harmonics up to the 25th order.
  • Arbitrary waveform
    Arbitrary waveforms are possible with 360 individually editable points. For ease of use, the arbitrary waveform can be derived from a sinusoidal, triangular or rectangular reference waveform.

List and Rectangle Editor

The „List“ function view offers the following functions and settings:

  • Defining a load profile in the chosen operating mode
  • Number of iterations
  • Synchronous data acquisition with individual sample rate for each load profile section
  • Loading a *.LST load profile
  • Saving the generated load profile as *.LST file (e.g. for direct list import from a USB mass storage device at the electronic load)

In the “Rectangular” function view, a simple square wave signal is defined by amplitude, offset, dwell time “Time High” as well as dwell time “Time Low”. From this, frequency and duty cycle are calculated and displayed.

The display elements of the measured value and status bar show currently measured values as well as important status signals of all available channels of the system.

The software supports the following data interfaces: RS-232, USB, LAN, GPIB, CAN.
