An Inverter drive (also known as AC Drive, Variable Frequency Drive, or VFD) is a motor drive device which regulates the amount of power supplied to a motor, allowing for precise control of speed or torque to the motor to suit its application. They are situated between an electrical supply and a motor. Electrical motors run many things we use in our society today and inverter drives are used for speed control in a range of applications, such as simple fan and pump loads. Inverter drives are also used widely in industrial applications for high torque machine control. Most inverter drives now have features such as digital operation and LED displays allowing for easy set-up, monitoring, and adjustment of parameters by the user.

Inverter drives are controlled by inputting specific frequencies or parameters into the device. When power goes through the drive the inverter adjusts the frequency and voltage that is supplied to the motor. They ensure that an electrical motor receives only the necessary amount of power it requires to function, in order to reduce waste or loss of electrical energy, thereby making it more efficient to run. They can also gradually ramp up power for a slower, safer machine start up. Inside the inverter, incoming AC power is converted to DC power via a rectifier made up of diodes, which is then smoothed to a clean, constant voltage by capacitors, and is then fed back out as AC power via output transistors.

Use this inverter drive from Rockwell Automation's Allen Bradley range to run your electrical motors efficiently. The 3-phase system lets you transmit high power, while the volts-per-hertz frequency controls enable you to safely regulate it. A user-friendly keypad, LCD (liquid crystal display) screen and quick-start setup make it fast and easy to install and program. Thanks to the industry-standard RS-485 communications interface, it's also simple to network with multiple devices.

• Compact size of 174mm in length and 72mm in width means it fits in tight spaces on your electrical circuit• IP20 (ingress protection) rating means it can withstand solid objects larger than 12mm• Feed-through wiring design makes it quick and easy to install

• CE (Conformité Européenne)• UL (Underwriters' Laboratories)• CSA (Canadian Standards Association)

This inverter drive enables you to control the speed of a motor, giving you greater flexibility of use. It can slow down or speed up your motor so it runs smoothly and efficiently, reducing wear and energy consumption.
