Control and Monitoring
The product control board exchanges data with the external controller through I/O signal and CAN communication. The control board drives on/off the switch tube of the module according to the control command transmitted by the external controller, records the module status information and transmits it to the external controller through communication, so as to obtain the status of product.
Cooling Method
The product adopts forced air cooling,and the cooling air is provided from the outside.
Note: Liquid cooling can also be adopted.
Structural Design
The product can be flat-mounted or hoisted.
A single module has small size and light weight,making it easy to maintain on site.
Diagnosis and Maintenance
The product hasa CAN maintenance interface and PTU maintenance software. By connec ting to the PTU through a computer, the operat ion data and status of the battery charger can be monitored in real-time.
At the same time, the PTU has specific fault diagnosis and fault recording functions. You can view the current fault status through PTU and download fault data to analyze and solve the problem.
Application Description
The product has been loaded in batches on the converters of China's Fuxing diesel locomotive, Electric Multiple Units and Malaysia's light rail vehicle.
