The load bank is expanded by 1+N load banks in parallel. The system consists of resistance, air cooling, electrical parameter inspection and control parts. It can be combined at will while ensuring that the gears are of the same resistance value when used in series. The customized load bank uses load-specific resistors, which are resistant to high temperature, corrosion-resistant, high precision and long service life. The load bank has a built-in resistive load bank; it can simulate any combination of various power loads. It is required for AC power supply tests such as battery testing and charging pile testing and full load testing. It is widely used in laboratories, production workshops, installation and commissioning, research and development. The performance parameters can be combined arbitrarily according to the test requirements to customize the discharge power. The host has temperature overheating alarm protection: if it overheats due to special reasons, the load can be automatically cut off. New power components with high power density. The axial flow fan has the characteristics of small air volume, good heat dissipation and low noise. It has a power input controlled by a type switch. The control cabinet is equipped with a control panel, which can be combined and controlled by switches on site. The digital display instrument is located in the control cabinet housing to monitor the electrical parameters (current, voltage, etc.). This series of load boanks has the performance characteristics of load addition and reduction control and testing.

1. Display function: Through RJ45 network remote communication and control, various charts, curves and test reports can be automatically generated. The data content is rich and the report is highly applicable. It can be signed and formatted according to user needs, and can automatically display environmental test parameters such as humidity, atmospheric pressure, and record temperature; according to the unit number and engine number and the test year, month and day, the test report and historical record files can be automatically retrieved, displayed, and printed.
2. Remote control: Remote intelligent monitoring and load test operation through the upper PC
