AJR2 Series Motor Soft Starter:Water Pump: with the help of water pump's control function to reduce the water- hammering...
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.
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.
