Optimise your system performance and gain cost-effective, dependable motor control with the PowerFlex 523 AC Drives by Allen Bradley. These inverter drives support a wide range of motor control applications and ensure greater ease-of-use to help you maximise productivity and reduce downtime.

These innovative and versatile units have a modular design which allows quick and simple installation and configuration, and they are perfectly suited for use with standalone machines. They also offer flexible mounting options, USB programming, and application-specific configuration to suit your needs. These AC drives also offer a compact footprint and can operate at temperatures as high as 70°C.

The Allen Bradley PowerFlex 523 drives offer a power rating of 0.2...22 kW (0.25...30 Hp) with global voltage classes of 100...600V. These AC drives have 3-Phase input and feature an EMC filter. QuickViewTM, AppViewTM and CustomViewTM tools enable easy operation and parameterisation. These devices support flexible installation options and save valuable panel space due to their compact footprint. The Economizer mode and energy monitoring features can also help to reduce energy costs. An integral human interface module (HIM) supports multiple languages and features descriptive.

Optional EtherNet/IP card (stock-no. 793-4547) supports ring topologies and device level ring (DLR) functionality.

• Integrated RS485/DSI port allows low-cost networking
• Space-saving modular design with an innovative removable control core, which allows simultaneous installation and software configuration
• Supports side-by-side mounting with 50 mm (1.96 in) air-flow gap at the top and bottom of the drive
• Wide range of motor control such as volts per hertz, and sensorless vector control (also with Economizer mode)
• Can operate in high temperatures up to 70°C (158°F) with current derating and a control module fan kit

The 25A-D017N114 PowerFlex 523 unit by Allen Bradley is a 3 Phase drive with an output current of 17 Amps and a power rating of 7.5kW, with voltage class 480 V ac. The enclosure has ingress protection of IP20 (Open) and is Frame size C.

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 management 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 AC drives are used for speed regulation in a range of applications, such as simple fan and pump loads. These units are also used widely in industrial applications for high torque machine control. Most 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.
