PXe-DL Series Electronic DC Load

Industry’s Easiest-To-Use DC Load 




PXEe’s DL Series Electronic Loads are available in multiple configurations to meet your unique application requirements. The DL series electronic DC load are extremely friendly and easy to use. Equipped with a full colour LCD touchscreen display, the unit can quickly be set up for your next production test. In addition, the DL is equipped with a comprehensive self-test that ensures that all loading and measurement circuitry is functioning properly.

Extremely Flexible in a Variety of Applications 

The DL Series is equally at home generating kW, W, mW or μW loading. Whether you are performing tests for LED drivers, batteries or battery chargers, the DL Series is a good choice for these applications.

Maximum Accuracy — Maximum Features 

The unit is fully featured with transient and wide band non-linear loading capabilities along with the additional feature of sweep capability. The DL Series Electronic Load provides high accuracy measurements (± 0.05%) of voltage and current with sweep steps as short as 20μs and pulsed loading up to 100 kHz. Units are fully configurable for loading, riding and falling edge controls and soft-start capabilities. The DL Series provides excellent transient performance in timing and wave shape with the ability for the user to view the current and voltage waveforms using the internal scope. The device provides fully protected short loading with automatic current and power limiting.

Unequaled Visibility of Test Results 

The DL Series provides graphical X/Y plotting of V vs I and V vs P characteristics using swept loading. In addition, the unit has a historical data logging capability, both graphical and numerical for additional test analysis and evaluation.

Flexible Integration in a Compact Package 

The DL Series is just 5” high, 8.5” wide and 13” deep, allowing easy integration into any test bench. The unit provides a variety of interfaces including LAN, USB Device & Host and Digital I/O. In addition, multiple units may be used in parallel for static higher power and current loading.
