Allen Bradley Inverter Drive, 0.2 kW, 1 Phase, PowerFlex 4M Series 240 V ac 2.5 A

Precisely control the speed of your AC (alternating current) motors with this inverter drive from Rockwell Automation's Allen Bradley range. The variable-frequency drive gives you volts-per-hertz control so you can start and stop industrial motors gradually and run them at optimum speeds. The built-in keypad and LCD (liquid crystal display) make it easy to program and accurately control your applications. Use this drive to run automated machines efficiently and prolong the lifespan of your motors.

• Feed-through wiring design makes it easy to install on new systems or fit on an existing setup• Programmable with computer software for increased control and easier maintenance• Mounts side-by-side with other drives to save you space• Adjustable PWM (pulse width modulation) frequency up to 10kHz allows for quiet operation

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

You can mount this inverter drive on any flat, vertical surface. Fix it to a 35mm DIN rail using the snap-on design or with screws using the rear mounting holes.

Experience powerful and precise motor speed control with PowerFlex 4M Single-Phase Input Frequency Controllers by Allen Bradley. These compact, cost-effective inverter drives are perfectly suited for machine level control. PowerFlex 4M drives offer application flexibility, feed through wiring and ease-of-programming to provide you with a streamlined and highly efficient motor control solution.

This drive is available in three frame sizes: A, B, and C, with power ratings from 0.2 to 11 kW (0.25 to 15 Hp) and in voltage classes of 120, 240 and 480 volts. Its ventilation system is only activated during motor operation, and it is silent when stopped, ensuring long service life.

• Pulse Width Modulation Frequency adjustable to 10 kHz for quiet operation

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.
