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.
Debug faster
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.
Software innovation
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
