DELTA VFD IN INDIA
Leading distributor and dealer of VFD from Delta in India
Overview
EKA is a leading dealer and distributor of Delta VFD in India. We distribute Delta VFD in Chennai, Bangalore, Pune, Mumbai, Ahmedabad, Hyderabad and Delhi.
A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively. Even though the drive controls the frequency and voltage of power supplied to the motor, we often refer to this as speed control, since the result is an adjustment of motor speed.
Benefits
In addition, today’s drives integrate networking and diagnostic capabilities to better control performance and increase productivity. So, energy savings, intelligent motor control and reduction of peak-current drawn are three great reasons to choose a VFD as the controller in every motor-driven system.
Common Uses of VFD
The most common uses of a VFD are for control of fans, pumps and compressors, and these applications account for 75% of all drives operating globally. Soft starters and across-the-line contactors are other, less sophisticated types of motor controllers. A soft starter is a solid-state device and provides a gentle ramp-up to full speed during startup of an electric motor.
An across-the-line contactor is a type of motor controller that applies the full line voltage to an electric motor.
