By adopting a current closed-loop control strategy, stable current output is achieved without being affected by load changes. Compared to the traditional testing method of voltage source+load+device under test, this method reduces capacity, energy consumption, and eliminates large capacity loads.
Product Features：
(1)Adopting a current closed-loop control strategy to achieve stable current output, unaffected by load changes. Compared to the traditional testing method of voltage source+load+device under test, this method reduces capacity, energy consumption, and eliminates large capacity loads.
(2) Adopting SPWM high-frequency inverter method to achieve constant current output, compared with motor regulated constant current source, the constant current accuracy is high, the response speed is fast, the distortion is small, and the efficiency is high. The temperature drift caused by external temperature changes can be ignored, which is the future development trend of industry testing
(3) High output current, with a maximum current of several thousand amperes, suitable for distribution cabinet busbars and circuit breaker aging testing
(4) Wide range of output current and frequency settings to meet the needs of different industries
(5) Built in electrical energy measurement circuit, capable of measuring parameters such as current, voltage, frequency, power, testing time, etc
(6) Fast dynamic response speed, with a response time of less than 20ms for sudden load changes
(7) The output current and frequency settings can be adjusted in real-time and the output can be updated immediately
(8) The key technical indicators of the whole machine adopt the concept of multi margin design, and the voltage stress, current stress, and heat generation have undergone strict technical verification and rigorous type testing, resulting in high reliability and long service life.
