2 产品型号 Model
ARD2 Series Intelligent Motor Protective Device (hereinafter referred to Protection), using the latest SingleChip technology, has the strong anti-interference capabilities, stable and reliable, digital, intelligent, network-based features. The protection can deal with many situations in the process of motor running such as overtime of starting, overload, phase failure, phase unbalance, underload, grounding/ leakage, the blocking, external faults and others, and with the accident record of SOE (Sequence Of Event) to facilitate maintenance personnel at the scene to find cause of the malfunction. It is suitable to coal, petrochemical, metallurgical, power, shipping and civil buildings, and other fields. The protection has long-distance communications ports of RS485, DC4 ~ 20mA analog output, is convenient to build a network with PLC, PC and so on. The remote monitoring of motor running is implemented.
