Typical connection of Motor management controller



ARD3 series intelligent motor protectors (hereinafter referred to as the protector), adopt advanced single-chip microcomputer technology which has many features like strong anti-interference capability, stable and reliable performance, digital, intelligent and networked, etc. Protector can protect motors from many faults during the motor running such as starting timeout, overload, locked rotor/block, phase failure, unbalance, under load, grounding, earth leakage, over voltage, under voltage, phase sequence, overpower, under power, temperature, external faults, etc. and is equipped with SOE fault event log function which is convenient for maintenance stuff to find the causes of the problems, and display the running  state clearly and intuitively through LCD in Chinese in four lines, status indicators and other ways. It is suitable for coal mine, petrochemical, metallurgy, electric power, shipbuilding, civil construction and other fields. The protector has RS485 remote communication interface and DC4-20mA analog output, which is convenient to form a  network system together with control machines like PLC and PC to realize the remote control of motor running.
