    Tips: How to choose a DC electronic load? 

    • Load Capacity: Determine the required load capacity based on your testing needs. ATO offers a range of DC electronic loads from 120W to 3000W, so select a model that matches or exceeds the maximum power capacity of the devices you intend to test.
    • Precision and Accuracy: Pay close attention to the load's resolution and accuracy, especially if your testing requires precise measurements. Look for a DC electronic load with the level of accuracy required for your specific application.
    • Operating Modes: Consider the types of operating modes the load supports. Most electronic loads offer constant current, constant voltage, and constant resistance modes. Ensure the chosen load can accommodate the testing conditions you'll encounter.
    • Safety Features: Safety is paramount. Check for built-in safety features such as overload protection, over-temperature protection, and short-circuit protection. These safeguards help prevent damage to your equipment and ensure safe testing procedures.

    By evaluating these four key factors, you can make an informed decision when choosing a DC electronic load from the ATO online store, whether it's for lower-power applications at 120W or for higher-power testing needs up to 3000W.
