Siemens VFD

Siemens VFD are the electrical devices that helps to control the rotor speed of the alternating motor and also helps to ramp up the speed for the smoother starting of the prime movers. These compact machines reduces the mechanical stresses on the drive units to increase the service life of the components. SiemenVFD Drive safes the energy consumption which improves the efficiency of theautomation systems and also reduces the cost of operation. They works by increasing or decreasing the frequency of the input voltage by converting the voltage twice with the help of high performance diodes, capacitors and transistors.
