Run the simulation
In the absence of three-phase power or load motor, the soft start
control loop can be tested, which is convenient for users to test.
Product Application
Protocol
The factory is Modbus protocol, and PROFIBUS communication protocol
can be customized, which can facilitate communication with German
Siemens PLC and touch screen.
PPT100 temperature sensor
Working with an external PPT100 temperature sensor, it can display
the motor temperature in real time and better monitor the
electricalMachine operation and protection of the motor.
Password control
After the user parameter debugging is completed, it can be locked
with a password to prevent others from changing the parameters. The
remote mobile phone APP function can be customized, remote control
can be used, and the soft start load operation can be monitored.
Easier to install
If the space of the motor control center is limited, using the
compact design of VKS-8000 can save space and eliminate unnecessary
troubles. The built-in bypass contactor, built-in monitoring and
indicator, and many control input and output functions can reduce
the installation space and cost of external equipment, and can also
simplify the installation.
