SA50B Controller
The rated input voltage of the SA50B controller is 250 ~ 420 V, the rated current is 140 A, and the weight is 5 kg. It can control one motor with a peak value of 100 kw. At the same time, it adopts control software based on the AutoSAR architecture, and also has the UDS diagnostic service and fault snapshot function of ISO14229. Whether it is the dexterous operation of industrial robots, the efficient power transmission of new energy vehicles, or the automatic environmental adjustment of building intelligent systems, it can rely on the adaptive adjustment mechanism to maintain stable operation in complex working conditions and changing environments, reduce energy consumption with excellent energy efficiency management, and extend the life cycle of equipment. The modular design gives it the ability to adapt flexibly, and the intelligent diagnosis function is like a dedicated doctor, always monitoring the health of the system, preventing problems before they happen, and continuously injecting strong power into equipment upgrades and industry intelligent transformation.
