Optimized fan performance: The electronic load tester features an intelligent fan system that automatically adjusts its operation to provide consistent airflow and stability across a wide voltage range, supporting reliable functionality. Diverse connectivity options: Dual current USB interfaces enable a variety of test setups and allow parallel connections to meet higher power demands without adding complexity. Efficient heat management: An upgraded power tube enhances fan speed and heat dissipation, enabling higher charging power levels while reducing the risk of overheating. Overheat safeguards: The builtin intelligent regulation feature helps protect the module from overheating damage during heavy use or overload conditions. Use scenarios Lab testing of power supplies, USB chargers, and charging modules to verify performance under realistic load conditions and ensure stable operation. Manufacturing quality control to simulate load scenarios, check thermal response, and validate safety features. Research and development to evaluate devices that draw current from USB interfaces, including configurations that use parallel connections for higher power testing.
