Allen Bradley 20BD156A3AYNARB0 Used Surplus

The Allen-Bradley 20BD156A3AYNARB0 adjustable AC frequency drive, also known as a variable speed drive or a variable frequency drive (VFD), operates with a 3-phase voltage of 480 Volts AC and a frequency of 50 Hertz. It also has an ampere rating of 156 Amps. The main function of the Allen-Bradley 20BD156A3AYNARB0 adjustable AC frequency drive is to control electromechanical or induction motors by varying its voltage and input frequency. By varying these 2 variables, the speed and torque can be controlled. The most common motors controlled by this kind of drive are those applied in fan and pump applications.

The Allen-Bradley 20BD156A3AYNARB0 adjustable AC frequency drive has a regular enclosure that protects the drive itself and its main connections. It is important that when installing the drive, vertical clearances are left between the drive and other equipment. This is done in order to allow proper ventilation and to avoid overheating. Frequent overheating can greatly reduce the life of the drive, and that is the main reason why heat should be avoided. The Allen-Bradley 20BD156A3AYNARB0 adjustable AC frequency drive has a 115 Volts AC standard control I/O and an RIO communication module. These 2 components combined with the full numeric LCD keyboard that comes integrated with the drive, enhance its functions. Through the communication module, the drive will be able to transfer data between the drives and the whole network and with the display, supervisors will be able to check data, input new variables, and change the whole process if needed. The Allen-Bradley 20BD156A3AYNARB0 adjustable AC frequency drive is intended for 3-phase applications.
