Product Description: The production and maintenance of DC charging pile, charging module, high-power power supply, battery, generator set and various electric power products all need to use high current discharge. Ws-6700 series DC load box solves the maintenance problem in DC power generation system, improves the safety and reliability of communication power supply and greatly reduces communication accidents, The long-term economic and social value created is immeasurable. Function introduction: 1. Daily maintenance and routine inspection of DC charging pile, battery and switching power supply equipment. 2. The test data of important parameters such as power, voltage and current are clear at a glance. 3. The user can set and adjust the discharge power, set the discharge time and timing time to automatically turn off the load according to the performance parameters and detection requirements. 4. It has constant current discharge function (optional). 5. Multiple parts can be discharged in parallel to adapt to the occasion of high current discharge. Application fields: It is mainly used in the aging test of wide voltage and high DC output power products such as DC charging pile, charging module, high-power charger, battery module pack and power supply. | |||
