Three Phase Thyristor AC380V 280KW Asynchronous Electric Motor Soft Starter Used To Control Fan

Three Phase Thyristor AC380V 280KW Asynchronous Electric Motor Soft Starter Used To Control Fancan start / stop motor smoothly, which avoids issues of shocks between mechanical and electrical caused by direct starting, star / delta starting, auto decompression starting and other traditional start mode.NKS100 Series motor soft starter is a kind of new motor starter and protection devices which combines power electronics technology, microprocessor and automatic control. It can also effectively reduce the starting current and distribution capacity, to avoid capacity investment. Meanwhile, current transformers are integrated in soft starter, users do not need to connect them externally.This product is three in line and six out line.

Description of Terminal

Conditions Of Usage

Features

★ Unique SCR Closed Loop Control Algorithm
Unique SCR closed loop control function designed specifically for standard loads and heavy loads. According to the load, the user can select the current limit start and the voltage ramp start to realize the smooth and smooth start effect without torque.
★ High reliability
High-performance microprocessor makes digital processing on control system, it avoids excessive adjustment on analog lines and achieves excellent accuracy and speed of execution.
★ Strong anti-jamming performance
All external control signals use Photoelectric isolation and set a different anti-noise level. It fits for special industrial environment application..
★ Easy adjustment method
With wide application range of control system, easy and intuitive adjustment. Through a variety of function options to match different types of control object.
★ Optimized structure
Unique compact design of internal structure, particularly user-friendly make it integrated into existing system. It saves costs of current transformer costs for users.
★ Adaptive power frequency
Power frequency 50/60 Hz, adaptive function, user-friendly.
★ Improved protection function
A variety of motor protection functions (Such as over-current, input/output phase default, thyristor short circuit, overheat protection, leakage detection, electronic thermal overload, phase current imbalance, etc.) ensures that motor and soft starter will not be damaged in case of failure or malfunction.
★ Easy to maintain
Monitoring signal coding system consists of four digital display, which monitors system equipment's working conditions, while providing rapid fault diagnosis.
★ Panel Can Be Cited
The panel can be led to the remote operation of the equipment operation surface through the body interface, which is convenient for field use.

Maintenance

1. Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
Brush the dust with clean and dry brush.
Remove dust with compressed air machine.
2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
(1) Blow it with a hair dryer or electric stove.
(2) Bring it to power distribution room for dehumidification.
3. Regularly check components' intact. Whether it can work properly.
4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
Before maintenance checking, it has to cut off all power in the line side of soft starter.

 Warranty: One year quality guarantee after shipment. More details please kindly contact with Noker Electric.Thank you!
