Ws AC load includes single-phase AC load, three-phase AC load, RL resistive load, RLC resistive capacitive load, RCD nonlinear load and other series. The products are widely used in daily maintenance test, engineering acceptance, factory inspection test and product aging of all kinds of switching power supply, medium frequency aviation power supply and inverter. It can simulate the test process of starting characteristics, stability characteristics, transient characteristics and output parameters of pure resistive, inductive, capacitive and mixed loads, and detect the performance of AC power supply when connected to different loads. The optimized subsection type is adopted for power input to meet the needs of different loads and different power factors.
Function introduction:
1. During the project acceptance of newly installed UPS equipment and generator set equipment, check whether the output power of ups and generator set equipment can meet the design requirements.
2. Routine maintenance and inspection of power supply equipment.
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. The load power factor can be set to ± 0.3 ~ 1.0（ Resistive load and resistive capacitive load (optional)
5. RS485 communication interface and Modbus RTU standard communication protocol are configured for system integration.
4. After loading, the voltage, current, active power, reactive power, apparent power, power factor, frequency and other parameters of the equipment to be tested can be measured.
5. By controlling the load through computer software, automatic testing can be realized, and the test data can be displayed, recorded and managed（ (optional)
6. The test data can be saved in the software database, the historical test data can be queried at any time, exported to excel and other general format files, and printing is supported（ Optional).
7. The load has multiple protection functions such as overvoltage, overcurrent, overheating and fan abnormality. It can be unloaded automatically in case of danger. It can also be unloaded forcibly through manual emergency stop switch（ (optional)
Application fields:
Test the output power and load capacity of AC charging pile ups, generator set, AC power supply, microgrid, inverter and other AC equipment.
