Product Overview
Description
Product Description
NJR2-ZX On-line Soft-Starter
1. General
NJR2-ZX Series on-line soft-starter is cored on advanced dualCPU 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 shortcircuit, 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.
3. Technical data
3.1 Power supply voltage: Three-phase AC380V (± 15%) 50Hz/60Hz (± 2%)
3.2 Starting current: 0.5 to 5 times the starting current limit
3.3 Ramp-down time: 0s ~ 60s
3.4 Base value voltage for soft starting: 30%Ue ~ 70% Ue
3.5 Kickstart Time: 0.1s
3.6 Environment requirements
Where the altitude is over 1000m, the capacity utilization should be reduced, current reduced by 0.5% for each additional 100m to 1000m; Ambient temperature of -10℃~40℃ (current is reduced by 3% for each 1℃ above 40℃); Relative humidity less than 95% Indoor environments featuring non-condensing, free of flammable and explosive gas, free of conductive dust, well-ventilated.
5. Features
5.1 Long-time online operation without requiring bypass contactor, saving installation space.
5.2 Intelligent Digital Dual SCM optimized control
5.3 Diversified advanced soft starting
5.3.1 voltage starting mode
5.3.2 Current limiting starting mode
5.3.3 Kick voltage + current limiting start mode
5.3.4 Kick voltage + voltage starting mode
5.3.5 Current ramp starting mode
5.3.6 Dual closed-loop starting mode
5.4 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
5.5 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 (see ① ②)
5.6 Display of operating voltage and current; fault code display and memory function (see ③ )
5.7 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. (see ④)
5.8 Unique master-slave linkage soft starting function, facilitating production process control of equipment.
7. Ordering information
7.1 Please select the required model and specification according to the instructions on model and meaning when ordering. Example: The controlled motor power of 45kW is installed and used with soft starting cabinet or matching distribution cabinet.
Ordering model: NJR2-45ZX
7.2 When motor with more than 4 poles is used with soft starter, recommend to select one size larger. Example: the controlled motor power 55kW is installed and used with soft starting cabinet or matching distribution cabinet. Ordering model: NJR2-75ZX
7.3 When bipolar motor is used with soft starter, as the starting current is large, please set the parameters correct as per the instruction manual before use.
7.4 For heavy load application, recommend the use of soft starter one grade larger.
