MEAN WELL Variable Speed Drives for Optimised Operations of Industrial Gates, Shutters, and Doors

Not entirely recent technology, Variable Frequency Drives (VFDs) or Variable Speed Drives (VSDs) have been around since the late 1970s and have proven its numerous reliable applications in a myriad of industrial operations over the years, worldwide.

In a bid to respond to sustainability and efficient energy use, MEAN WELL has developed its line of VFDs intended for DC brushless motors. 

What is VFD and its Industrial Applications? 

VFD is a type of electrical device that controls the speed of a tool or machinery. It works by intercepting electrical input and modifies it using Pulse Width Modulating (PWM) signals to produce the required output for a specific operation. In simple terms, it gives you full control of the motor's speed and torque to safely open or shut on command.  

Since VFDs only apply the required power according to your motor's energy needs, it helps reduce your electricity bill, lessen the chances of overheating and wear and tear, thereby extending the life of your motor.  

VFDs are best used when dealing with variable torque loads that do not always require full power, such as fire shutters, industrial doors, and gates. 

MEAN WELL VFD Product Range

MEAN WELL VFDs are available for low, medium, and high voltage motor requirements.  

VFD-150 to VFD-350P models have a maximum capacity of 48V and are designed to cater to smaller motors with low voltage needs. These models also take DC input voltage.  

For medium- to larger-sized motors requiring more power, VFD-250P to VFD-750C are the best options. These models are suitable for motors of up to 240V and accept AC input voltage. This range is also equipped with built-in Power Factor Correction (PFC).
