Delta Electronics VFD Drives
Contact Person: 01325074100
The Delta Electronics VFD-F Series is a Variable Torque AC Drive specially designed for medium and high-horsepower fan and pump applications.
This series features an adjustable V/F curve, automatic voltage regulation (AVR), and built-in PID feedback control, making it ideal for efficient and precise motor speed control.
It supports operation with up to four motors simultaneously — one variable-speed motor and three constant-speed motors — providing flexibility for industrial systems such as HVAC, water treatment, and large-scale water supply applications.
