20AD022A0NYNADNN

The 20AD022A0NYNADNN is a variable frequency drive designed and manufactured by Allen-Bradley. This unit, also known as an AC drive or inverter, takes a 3-phase 480 Volts AC rated voltage at 50 to 60 Hertz at the input side and it varies the speed of a 3-phase motor attached at the output side. It enables the users to run motors more slowly. This can save significant energy, and furthermore, this process leads to adjustable acceleration and deceleration which can soften the mechanical stress at the motor starting and reduce inrush current. The Allen-Bradley 20AD022A0NYNADNN can be used with 11 kW rated motors. The drive supports DeviceNet networking and it can be additionally customized with a variety of features that users can order separately. This includes an optional HMI terminal and configurable I/O.

The Allen-Bradley 20AD022A0NYNADNN is a member of the Allen-Bradley PowerFlex 70 adjustable frequency AC drive series that focuses on delivering a perfect and accessible variable frequency motor control process for applications that require constant speed and frequency control for their machinery to run smoothly. Electrically, proper installation and control of the drive are important. The manufacturer does not recommend using contactors or disconnect switches on the supply side of the drive. This is a recommended thing to do only in emergency situations. Opening a contactor or similar device at the input side of any AC drive while the motor is still running can cause trouble for the unit and reduce its operating life. The construction of the 20AD022A0NYNADNN module is robust enough to withstand operation in a standard manufacturing environment.
