Typical connection of Motor control and protection unit


Smart motor protectors ARD2F series (hereinafter referred to as the protector), utilizes advanced single-chip microcomputer technology which has many features like strong anti-interference, stable and reliable running, digitalization, intelligence and networking, etc. Protector can protect motors from many faults during the motor running such as timeout startup, overload, locked rotor/block, phase failure, unbalance, under-load, earthing, 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 industry, metallurgy industry, power industry, shipbuilding, civil buildings 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 monitoring of motor.
