AJR2 Series Motor Soft Starter

ApplicationsWater Pump: with the help of water pump's control function to reduce the water- hammering phenomenon when switching on and cutting off, and save the cost of system maintenance. Ball Mill: by means of double slopes voltage starting to reduce the abrasion of gear torque and the maintenance workload, economize time and save cost Fan: soft starter replaced the traditional starter to reduce strap fretting and machine impact, save the cost of maintenance Compressor: make use of the current limiting starting or double slopes starting to realize smooth starting, reduce motor heating to lengthen its service life Crusher: make use of locked rotor and swift protection to avoid mechanical failure or block, which will cause electromotor superheating to result in burning. Conveying Machinery: running by soft starting and presetting at low speed to realize the smooth and gradual superconducting overall process and avoid the replacement of products and liquid spilling.Features:Adopt sixteen Single-Chip computer all-digital automation control. The connection mode of major loop is three in, six out to realize on-line protection of the whole series. Major devices adopt the silicon-controlled modules manufactured by Sanshya Corporation in Japan; CPU adopts Philips' CMOS chip. Starting torque' current, voltage, time can be set flexibly according to different load to attain the first- rank current impulse and torque control. Provide smooth and gradual advancing starting process for motor, reduce the impulse of starting current to electrical network, diminish equipment' vibration and noise, lengthen the service life of machine's transmission, and improve workers' working conditions. Starting current can be adjusted according to load to reduce the starting loss, and get the best torque at the minimum current. Soft stop greatly lengthens the electrical contact service life and meets the requirements of machines on different occasions. Bearing over-current, over-load, phase shorting of power supply, etc. multiple protection to ensure the safety of both equipment and electrical motor. The output voltage of soft starting device rises in accordance with the assumed rules; to make the controlled electrical motor torque finish starting process under the optimal accelerating curve, then exit thyristor module to let bypass contactor work. Convenient outside control interface provide various functions: digital delay starting control, soft stop control input, starting delay relay output, faults relay output. Phase sequence can be identified automatically and owns the phase sequence protecting function. Both free stop and soft stop are available, and the time of soft stop can be adjusted. All-digital setting and outside control function greatly facilitate the users. With the standard RS232C/RS485 interface. Novel structure, small size, reliable performance, simple installation and operation.AJR2 Electric CharacteristicsStandardAJR2 developed the electronic formula Soft start-Soft stop device and passed the significance test, which is up to the national standard:(GB 14048.6-1998).Three-Phase Source Voltage(U)V208-10%...240+10%380-15%...415+10%440-15%...500+10%FrequencyHz50Nominal CurrentA10o≠1000 totally 20 kinds of rated valueMotor PowerKWMotor rated plate voltageVCurrent RegulationThe nominal current of motor In can be regulated in the range of 0.5 1.3 times of starter's rated current.The maximum starting current can be regulated in the range of 2 7 times In, within 5 times of the starter's current limitation.Start-up ModeThe starting current is limited in 5InSetting before factory leaving: when torque integral are 16 seconds, to the standard load, the current is 3In; when torque integral are 15 seconds, to the heavy load, the current is 3.5 In.Stop ModeFree stop4 seconds, soft stopSoft stopIn the range of 0.5 60 seconds, can be adjusted by programmingBraking stopIn the range of 0.5 60 seconds, can be adjusted by programming (Order Agreement)Display and KeyboardWhen operating normally, the working current (or the current percentage) of electrical motor can be showed; when operating at faults, the malfunction contents will be displayed.Keyboard are available for parameter setting-up and points setting-up and lock-in.Output Relay (2 pieces)JRJ MTypes of Contact1"NO"+1"NC"1"NO"+1"NC"Setting before factory leavingOutput of the relay startingOutput of the malfunctioning relayMaximum working power 220V VAStarting Power: 1200Holding Power: 120Minimum switching capacity A100mA-24VNominal working current A0.5 Class AC-14, AC-15(240V AV)& DC-13(48VDC)Nominal thermocurrent A5Maximum working voltage 400VService life5×108timeProtectionIntegrated protection to both motor and starting deviceMain power supply protectionPhase shorting protection and phase imbalance protection, displayed by output relaySelective StarterAJR2 device can be chosen according to the nominal power and load of motor.Starter's power can be used for standard load and heavy load.
