Allen Bradley 20BD077A3ANNAND0 Used Surplus

The 20BD077A3ANNAND0 is an adjustable frequency AC drive that has been used in the control industry as a mechanism to prevent motor wear due to sudden operations. This drive belongs to the Powerflex 700 series, specifically frame 4. It has been designed and distributed by Allen-Bradley. The Allen-Bradley 20BD077A3ANNAND0 adjustable frequency AC drive basically consists of three elements which are: a rectifier bridge converter, an inverter, and a DC direct current link. The main mechanism is to modify the motor input values such as voltage and/or frequency in order to vary speed and torque. This drive provides different mechanisms to control the motor. It also provides a soft stop, soft acceleration, and a soft start. This way, the motor will not suffer from excessive wear due to sudden speed changes. It also provides energy savings.

The Allen-Bradley 20BD077A3ANNAND0 adjustable frequency AC drive comes with a NEMA 1 enclosure that grants protection to the drive against solid particles that might threaten to enter and impede its proper functioning. This enclosure makes the drive reliable in front of the users since there will not be loose connections and all the wiring will be enclosed and preserved from any damage. The Allen-Bradley 20BD077A3ANNAND0 adjustable frequency AC drive is able to operate at a maximum ambient air temperature of 40 degrees Celsius. Before proceeding with the installation of the drive, clearances need to be left in order to receive good ventilation. If not, it is recommended to install a different method that provides ventilation. The Allen-Bradley 20BD077A3ANNAND0 adjustable frequency AC drive has a Vector I/O and a Human-Module Interface that enables the proper programming of the drive.
