5.5KW to 500kw bulit in Bypass Soft Starter for ac motor protection
Product feature
VKS-8000 is a highly intelligent, very reliable and easy to use soft starter. The newly designed functions of VKS-8000 are used for quick setting or more personalized control.
It's a perfect solution. Its performance includes:
Large LCD screen that can display feedback information in Chinese and English languages, other languages can be customized.
Remotely installable operation panel.
Intuitive programming.
Advanced start and stop control functions.
A series of motor protection functions.
Extensive performance monitoring and event logging.
More control
VKS-8000 soft starter adopts a new generation of soft start technology, and adaptive control realizes the control of the motor acceleration curve and deceleration curve to an unprecedented level.
The soft starter reads the data of the motor in the process of starting and stopping, and then adjusts to achieve the best effect. Just select the curve most suitable for your load type, and the soft starter will automatically ensure that the load is accelerated in the most stable way possible.
Easy to use
VKS-8000 is very easy to use whether it is during installation, debugging and use, or when troubleshooting.
- Quick setting can make the machine run quickly, the information screen can display various operating data, and the trip message can be displayed in language to explain exactly where the problem is.
- The control cable can be routed from the top, bottom or left. Very flexible and unique cable access and fixing devices make the installation faster and neater. You will soon experience how easy it is to use VKS-8000.
Multiple starting control methods
- A variety of starting methods can meet your various load requirements, and users can choose the starting method according to their own load conditions.
VKS-8000 simplifies the installation and operation of the motor starting system, thereby reducing installation costs and shortening installation time
