Acrel Smart Motor Control and Protection Ard2-25/C with RS485 Communication Panel Installation LED Display

Product Description

Product Description

ARD series intelligent motor protector (hereinafter referred to as protector) can perform various conditions such as start timeout, overload, phase failure, unbalance, underload, ground/leakage, blockage, short circuit and external fault during motor operation. Protection, and SOE fault event recording function, convenient for on-site maintenance personnel to find the cause of the fault. Suitable for coal, petrochemical, smelting, electric power, ships, and civil construction. The protector has RS485 remote communication interface, DC 4 ~ 20mA analog output, and PLC, PC and other control machines form a network system. Remote monitoring of motor operation.
