4.8KW DC Load Bank Suitable For The Test Of Energy Storage Equipment
The DC load testing equipment adopts a 4U standard rack-mounted design, which is convenient for installation and transportation.
Dual voltage support: The device supports the switching and use of two voltages, DC120V and DC48V, which is highly adaptable and can meet the testing requirements of different devices and systems.
High-precision resistors: Sheet resistors with ±3% accuracy are adopted to ensure stability and accuracy under different load conditions, providing reliable test results.
Forced air cooling system: Equipped with 15050 fans, it adopts forced air cooling, dissipating heat from the front to the back to ensure the stability and safety of the equipment during high-load operation and extend the service life of the equipment.
Multiple protection mechanisms: The equipment is equipped with overheat protection, overvoltage protection and emergency stop functions, ensuring that the power supply can be quickly cut off in abnormal situations to protect the safety of the equipment and personnel.
Current range: It offers multiple current range options at DC120V and DC48V. Users can flexibly adjust them according to their actual testing needs to meet the testing requirements of different devices.
Real-time monitoring and display: Equipped with digital display function, it can show parameters such as voltage, current and power in real time. Users can understand the operating status of the equipment through intuitive digital display, which is convenient for timely discovery and solution of problems.
Power system testing: During the research and development, production and maintenance of the power system, the JH-RYF-4.8KWD120D48-W7A-4U DC load cabinet can simulate different load conditions to conduct performance tests on equipment such as generator sets, transformers and switch cabinets, verify their operating conditions under different loads, and ensure the stable operation of the power system.
In the field of new energy: This load cabinet can be used to test the performance of equipment such as inverters and energy storage systems, simulate different load conditions, and detect parameters such as output voltage, current, and power of the equipment, providing data support for the optimization and upgrade of new energy systems.
