45KW 55KW 75KW 90KW 110KW online soft starter for ac motor protection
Product description:
VKS-6000 is the latest development of online soft starter, is a new type of motor starting equipment developed by the international advanced level
based on power electronics technology, microprocessor technology and modern control theory and technology, which can effectively limit the starting voltage when starting the motor It can be widely used in overloaded equipment such as fans, pumps, conveyors and compressors. It is an ideal replacement for step-down starting equipment such as star / delta conversion, self-coupling buck and magnetron buck. No need to install a bypass contactor, greatly reducing user costs.
Key Feature
1, Six group parameters convenient in one soft starter to different power motors load.
2, Dynamic fault recording function and Inspecting motor feedback to realize closed loop control to give best motor start up in different conditions and different loads.
3, A variety of ways starting:voltage RAMP starting way can get the maximum output torque;Current limiting can realize biggest Limitations of the Start soft starting current.
4, Reliable quality Assurance:using computer simulation design;SMT Production process;Electromagnetic Compatibility Excellent.
Performance;High temperature aging,Vibration Test before delivery of the machine.
Product technical characteristics
Main circuit working voltage: AC380V (+ 10% ~ - 25%); Main circuit working current: 22A ~ 560A;
Main circuit frequency: 50Hz / 60Hz (± 2%); Soft start rise time: 2 ~ 60s;
Soft parking time: 0 ~ 60s; Current limit multiples: 1.5 ~ 5.0Ie; Initial voltage: 30% ~ 70% Ue; Cooling method: fan cooling;
Communication method: RS485 serial communication;
Installation easier
If the motor control center has limited space, using the compact design of the VKS-6000 saves 70% space, eliminates the need for bypassing the contactor, and reduces primary and secondary costs by more than 30%.
Stop smoother
The CPU also provides precise control of soft stops for applications that require smoother soft stops.
CPU for small inertia loads, such as pumps and conveyors, can greatly reduce or even eliminate the water hammer effect.
The VKS-6000 is easy to use at design time considering the ease of use menu is not surprising. After installation, the quick setup menu assists you in configuring the starter for common applications: it suggests a typical value that you can fine tune to your own needs, all with an easy-to-use dashboard.
A wider range of applications Built-in smart power motherboard, but Paul remote places, low voltage or voltage instability led to the device can not get up, intelligent power supply board can be within the voltage 150V- 460V application equipment to achieve the normal starting requirements.
New current-voltage coefficient, built-in power board can be directly calibrated current and voltage.
Start delay parameters, when the equipment power failure, the soft starter automatically delayed after 5 minutes
