20AC011A3AYNANNN

The Allen-Bradley 20AC011A3AYNANNN is crafted to operate 3-phase 400 Volts AC supplied systems. It is part of the PowerFlex 70 series of AC drives that are used to change the speed of 3-phase motors. This device has more capabilities than the motor and that is why the motor coupled with an AC drive can achieve much more than is possible with just the motor. When the motor speed is controlled by the 20AC011A3AYNANNN, it will save energy and reduce mechanical wear on the system parts. Harmonics, voltage rise times, and voltage spikes have much less influence on the motor because this AC drive has sophisticated filters. The unit is also equipped with other components that have the ability to minimize unwanted heating and insulation damage to the motor.

The Allen-Bradley 20AC011A3AYNANNN has surge suppression gadgets that safeguard the drive from overvoltage and short circuits. The drive is intended to be used with 7.5 Horsepower rated motors that have 11.5 Amps of nominal current. When installing the drive, take into consideration the fact that it can encounter certain conditions that might call for line isolation or for a reactor for the unit. It is very important to provide a stable voltage source to the device, otherwise, it is possible to encounter overvoltage faults, nuisance power blowing, or even damage to the device. The Allen-Bradley 20AC011A3AYNANNN should be installed in a control cabinet by attaching it to a panel. This drive contains electrostatic discharge-sensitive assemblies, so precautions for static control are required when installing, servicing, or testing this unit. Always leave the device for 5 minutes to discharge its capacitors after the shutdown and before starting any maintenance procedures.
