Product Description: Ws-6500 series - AC electronic load shall be mainly used for on-line commissioning, off-line detection, aging test and function verification of AC charging pile products, which can truly simulate the charging process and various faults, and avoid inconvenient test use, incomplete test content and inability to simulate real faults caused by using real electric vehicles as detection devices, At the same time, it can also avoid the damage of the test vehicle caused by the failure of the charging pile. Our equipment can accurately measure the output power and load capacity of the charging pile. Function introduction: 1. During the project acceptance of newly installed AC charging pile equipment, check whether the output power of DC charging pile equipment and battery can meet the design requirements. 2. Daily maintenance and routine inspection of AC charging pile equipment. 4. The test data of important parameters such as power, voltage and current are clear at a glance. 5. All high efficiency electric heating elements comply with UL safety specifications. 6. It has fan fault detection, overvoltage, overcurrent, leakage and other protection functions. 7. Programmable support RS485 communication interface, Modbus RTU standard communication protocol. Application fields: Test the output power and load capacity of AC charging pile.
