VFD Control Panel

Types Of VFD (Variable Frequency Drives) Panel We Offer

VFD Control Panel

Motor Control VFD Panel 

Almost every control panel has some form of motor control circuitries and one of those circuitries is most likely utilizing a VFD to control the speed, direction, and start/stop of a motor. Keltour has the full capability in designing and manufacturing  of VFD panels according to your needs and specifications; from fractional horsepower to large 500 Horsepower motors at various voltages.

Conveyor Control System VFD Panel 

Keltour VFD conveyor system panels are used in many industries as a standard piece of mechanical equipment to move goods, products, and other materials from one location to another which requires a precision control of movement between groups of motors. We specialized in VFD control panel design and build for various types of conveyor systems.

Explosion proof VFD  Control Panel 

VFD panels located in hazardous areas are becoming more mainstream.  With the panel located closer to the field, it reduces the installation cost where the installer doesn’t have to run long distances for cable installation compared to if the panel has to be located in a non-hazardous area.  Keltour has the capability to design and build VFD panels to various industry standards such as, but not limited to, Class I & II, Division 1 & 2 (Zone 1 & 2). They can be designed using various types of techniques such as in an explosion proof enclosure or purging and pressurization system.

 A VFD is a motor control system that regulates an electric motor by adjusting the speed and power output provided to said motor. VFD panels vary in purpose and usage. However, they generally require a customized manufacturing process based on the particular operating condition that is meant to power and control. Some of the industries VFD are used in are Water, Mining, Process, and all kinds of Commercial & Industrial applications. 

VFD panels have an enclosed framework. Their protection rating is commonly typically Nema1 (IP) 20, 21, and 30 all the way to Nema 4X where weatherproofing and waterproofing is absolutely necessary to protect the integrity of the panel.

Despite the fact that the variable frequency drive (VFD) control panel regulates the frequency and voltage of the power supplied to a given motor, it is common for this application to be referred to as speed control because the outcome of an alteration of this device is motor speed.

 A variable frequency drive (VFD) is a durable device that accepts alternating current (AC) and direct current (DC) power as inputs and delivers a voltage and frequency output to the specific motor in a controlled and safe fashion. 

The VFD panels safeguard the electronics connections from potential dangers by safely housing the VFD as well as other elements. They also have integrations for easy real time control, as well as cost effective displays for viewing all information and statistics concerning the operation of the VFD motor and process. The breakers located within the enclosed panel protects the VFD from experiencing spikes in voltage, and the control system can be utilized to modify the speed of the motor to your preference.

The overall control panel is made up of VFDs, and other components, including:

  • Relays, circuit breakers, stabilizers, and other forms of protection equipment.
  • A bypass control that allows the VFD to continue operating in all environments.
  • PLC for enhanced functionality.
  • Harmonic filters.
  • Line reactors
  • Switches, modems, and other types of communication equipment.
  • Anti-condensation, heaters, air conditioners, and other types of HVAC temperature control devices.

You should maintain your VFD control panel approximately every six months to ensure that it can operate to its fullest capacity at all times and to prevent damage.

There are numerous advantages to VFD control panels. These advantages include:

Protection and the ability to switch the level of power to a device

VFD panels are generally designed with a power switch that is hooked up to the input current power source to toggle the panel on and off. In addition, VFDs protect the circuits, and adjustable speed drives whenever a short circuit or overload takes place. At the same time, the power can be disconnected by VFD panels to ensure safety on site throughout motor upkeep procedures. 

Modifiable levels of speed

A voltage regulation device is implemented on the VFD panel’s door to send a control signal to the motor based on the delegated controls. The variable frequency drive control panel has a primary switching component to make sure that the system continues to function if a variable frequency power failure occurs.

 Visual graphic control

The screen and operation panel on the front part of the VFD panel are connected to an electrical element inside the control box. It can visually display the panel’s operating capacity and is helpful in controlling the motor in actual real-world operational processes.

 Safety protection

 The variable frequency drive and all other electrical features are connected inside the variable frequency panel, lowering the impact of external surroundings on the electronic system, such as reducing the shock hazard rate. This ultimately increases safety.

Extends the life of your equipment 

When your machinery is monitored by VFDs, which achieves optimal motor implementation frequency, it will operate longer over the years and require less maintenance which will maintain your workplace productivity.
