20AC011A0AYYANC0

The Allen-Bradley 20AC011A0AYYANC0 Variable Frequency Drive (VFD) is a member of the Bulletin 20A product family of variable frequency AC drives that has a relatively large size (it comes in a frame size of Frame C) and it contains an internal brake resistor that dissipates the regenerated voltages received from its motor loads as heat. The Allen-Bradley 20AC011A0AYYANC0 Variable Frequency AC Drive can handle a current rating of 11.5 Amps, a Horsepower rating of 7.5 Horsepower (5.5 kilowatts), and it uses a 3-phase operational voltage of 400 Volts AC, 50 Hertz. Another special characteristic of this variable frequency AC drive is that it comes with EMI filtering as a standard feature and not as an additional option like with the other products in the same family.

The manufacturer recommends a panel mounting installation of the Allen-Bradley 20AC011A0AYYANC0 Variable Frequency AC Drive inside an IP 20, NEMA/UL Type 1 enclosure with an adequate forced ventilation system or climate control equipment that is  able to handle the high temperatures produced by the IGBT braking/internal braking resistors. This device should be configured by the implementation team during commissioning by adjusting the enhanced control parameters to meet the requirements of the specific systems. No feedback from external devices is received by this drive, and there are no HMI appliances built into the Allen-Bradley 20AC011A0AYYANC0 Variable Frequency AC Drive, so the initial configuration is key for correct product operation. Because this VFD does not offer networking or communication ports, it is mostly suitable for remote installations or single-motor application processes that require smooth operation with specific speeds and torque control and that need to change the direction of rotation in a motor.
