NJR2-ZX Series on-line soft-starter is cored on advanced dual-CPU control technology. It controls SCR  module, realizes soft starting & stopping of three-phase AC induction motor (squirrel cage type), and has wide range of protection functions e.g. overload, input phase failure, output phase failure, load short-circuit, starting limiting overtime, over-voltage, and under-voltage. 

After starting motor, the product does not require bypass contactor, with power specifications covering 7.5KW ~75KW; widely used in electrical drive equipment in the fields of metallurgy, fire, mining, water supply, municipal administration, food,cement and petrochemical. It is an ideal updated product of traditional star - delta starter, and self-coupling voltage starting. 

Features:

• Long-time online operation without requiring bypass contactor, saving installation space.
• Intelligent Digital Dual SCM optimized control
• Diversified advanced soft starting
• voltage starting mode
• Current limiting starting mode
• Kick voltage + current limiting start mode
• Kick voltage + voltage starting mode
• Current ramp starting mode
• Dual closed-loop starting mode
• Built-in overload, input phase failure, output phase failure, load short-circuit, start current limiting timeout, over-voltage, under-voltage overheating and other protection functions.
• Wide-body large LCD displays are in both Chinese English, the operation is more humane and the operation and parameter settings are more simple and man-machine dialogue is achieved
• Display of operating voltage and current; fault code display and memory function 
• RS485 communication function (requiring extended RS485 communication module), facilitating networking control and automation engineered; providing three relay outputs: operating, ramp-top and failure for external linkage control.
• Unique master-slave linkage soft starting function, facilitating production process control of equipment.
