1. High-precision parameter measurement: Equipped with advanced high-precision sensors, the voltage measurement accuracy can reach ±0.05%, and the current measurement accuracy can reach ±0.1%, which can accurately capture the slight changes in the electrical parameters of the charging pile. When testing a charging pile with an output voltage of 220V, the equipment can detect a voltage deviation of 0.11V; for a charging pile with an output current of 32A, the measurement error can be controlled within ±0.032A, providing a reliable data basis for the performance evaluation of the charging pile. - 2025-06-18How does intelligent control technology improve the efficiency and performance of load banks?
• Accurate load regulation: Intelligent control technology uses advanced algorithms, such as PID control algorithms, to accurately adjust the load according to the set value. Whether it is resistive, inductive or capacitive load, it can quickly and stably reach the preset load level, avoiding the over-adjustment or under-adjustment that may occur in traditional manual adjustment methods, thereby improving the accuracy and efficiency of the test. For example, when testing power supply equipment under different load conditions, the intelligent load bank can accurately adjust the load size according to the preset load change curve, simulate various load conditions in actual applications, and provide accurate data support for the performance evaluation of power supply equipment.
