AC380V 50/60Hz 220KW Built-in Bypass Squirrel-Cage Asynchronous Electric Motor Soft Starter is widely used in fan start and control.

★ Various start-up mode
User can select current-limit starting mode or voltage ramp starting mode. In order to meet site requirements in maximum extent and to achieve the best start effect, you can also impose a programmable jump starting and starting current-limit under each mode.
★ 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 and bypass contactor costs for users.
★ Adaptive power frequency
Power frequency 50/60 Hz, adaptive function, user-friendly.
★Analog output
4-20mA current output function, user-friendly
★ MODBUS-RTU Communication
During network communications, it can connect up to 32 devices. Users can achieve the purpose of automatic communication by setting baud rate, communication address. The setting range of communication address is 1-32, The factory value is 1. The setting range of communication address is 0,2400; 1,4800; 2,9600; 3,19200. The factory value is 2 (9600).
★ Improved protection function
A variety of motor protection functions (Such as over-current, input/output default phase, thyristor short circuit, overheat protection, leakage detection, electronic thermal overload, internal contactor fault, 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.
NKS200 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 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. It can also effectively reduce the starting current and distribution capacity, to avoid capacity investment. Meanwhile, current transformers and contractors are integrated, users do not need to connect them externally.

Typical Application
Fan Control Soft Starter For Three Phase Induction Motor AC380V 50 / 60Hz 220KW

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.
