  • Product Description
OBC&Inverter Test Cooling SystemOBC&Inverter Test Cooling SystemOBC&Inverter Test Cooling System
OBC (onboard charger) and DCDC (DC-DC converter) are the core components of electric vehicles, and the functional quality of DCDC and OBC is critical to the performance and safety of the entire vehicle. During the development and testing of OBC and DCDC, as well as the entire vehicle, a comprehensive test of the functions and performance of OBC and DCDC is required.
OBC&Inverter Test Cooling SystemOBC&Inverter Test Cooling System
Touch screen digital display, the device is equipped with a communication interface, all data can be exported by U disk; the liquid filling indicator clearly shows the location of the heat transfer medium.
OBC&Inverter Test Cooling System
Emerson Copeland / Danfoss scroll flexible compressors, all refrigeration controls are international brands, high temperature control accuracy, fast cooling speed
OBC&Inverter Test Cooling System
Multi-channel temperature and flow control, one device can realize multi-channel output, and each channel can control different flow;
The device can choose not only to control the flow, but also to control the pressure;
At the same time, it is equipped with a powerful circulation pump to ensure the delivery of high-viscosity liquids and can provide high flow rates under stable pressure
