Replace MB85RS128, Ferroelectric Memory GX85RS128 for Power Arc Light Protection Devices

Arc light protection device mainly realizes the protection function by detecting arc light and overcurrent in the circuit. When arcing and overcurrent occur in the circuit, the protection device will immediately issue a trip signal to cut off the fault point to protect the safe operation of the power system. Therefore, the role of the arc light protection device in the power system is very important. It can detect the arc light and overcurrent in the circuit in time, and quickly cut off the point of failure to protect the safe operation of the power system.

Power arc protection devices need to quickly and accurately record and store critical power parameters and event information to achieve timely detection and response to potentially dangerous arc faults. This paper introduces the ferroelectric memory GX85RS128 applied to the storage module of this device. The fast writing capability of the GX85RS128 enables it to store the data related to the moment of arcing in a very short period of time, ensuring that no important information will be missed.

The non-volatile characteristics of the ferroelectric memory GX85RS128 allow the data stored in the ferroelectric memory to be retained intact even in the event of power supply interruptions caused by sudden faults in the power system. This facilitates subsequent fault analysis, cause tracing and system recovery. Main Parameters Introduction:
