Control and Monitoring
The product control board and external controller complete data exchange through I/O signals and CAN communication. The control board drives the opening/closing of each switch tube based on the control command transmitted by the external controller, and records the stat us
information of the charger, which is then transmitted to the external controller through communication for easy access to the status of the product.
Cooling Method
With a cooling fan for forced air cooling and heat dissipation.
Structural Design
The product adopts a flat installation inside the vehicle, and the main material of the box is stainless steel.
The entire product is lightweight and easy to maintain on site.
Diagnosis and Maintenance
The product is equipped with RS232 maintenance interface and PTU maintenance software. By connecting to the PTU through a computer, the operation data and status of the 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 is used in batch on ALSTOM-CORADIA LINT DMU
