Allen Bradley Inverter Drive, 400 W, 3 Phase, PowerFlex 4M Series 480V ac 1.5 A

Regulate the power supply to your AC (alternating current) motor with this inverter drive from Rockwell Automation's Allen Bradley range. Using the built-in keypad functions or computer software, you can programme and adjust the output to suit your needs. These flexible controls let you accurately set the output frequency and schedule acceleration and deceleration times to efficiently run machines. A pre-charged relay and overload protection safely control the electric current. Install this drive on your electrical circuit to streamline your automated conveyors, pumps and air-conditioning units.

• Three-phase inverter for use with high-power and high-torque machines• Feed through wiring to help make installation quick and simple• DIN rail and screw mounting options for increased flexibility• Adjustable PWM (pulse width modulation) frequency to minimise workplace noise

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

A quick-start function means you can get the device up and running rapidly without the need for extensive programming or networking.

Ensure precise and powerful motor speed control for your application with PowerFlex 4M Triple-Phase Input Frequency Controllers by Allen Bradley. These affordable, compact inverter drives are ideal for standalone machine level control. PowerFlex 4M drives offer feed through wiring and ease-of-programming to provide you with a streamlined, flexible, 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.

• Power ratings from 0.37 to 11 kW in triple phase 400 V

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.
