20G21ND8P0JA0NNNNN

The Allen-Bradley 20G21ND8P0JA0NNNNN variable frequency drive is a PowerFlex 755TS series motor control drive. It is widely deployed for motor control in industrial applications. The 20G21ND8P0JA0NNNNN drive supports several advanced technologies, including TotalForce technology for motor control, Load Observer technology for adaptive control, Ride-Through technology for protection against power disturbances, and TorqProve technology for coordination between the motor torque and brake operation. The output ratings of the 20G21ND8P0JA0NNNNN drive are dependent on its operating conditions, input voltage, and whether the drive is connected to a 3-phase or single-phase AC input voltage source. The full rated output requires 3-phase input voltage in a range between 460 and 528 Volts AC, and drive operation under specified ambient conditions. The 20G21ND8P0JA0NNNNN variable frequency drive also supports 650 Volts DC voltage.

The continuous output current rating of the Allen-Bradley 20G21ND8P0JA0NNNNN PowerFlex 755TS series variable frequency drive is 8 Amps. The frame size of the drive is Size 2. The rated output power for normal duty operation is 5 Horsepower. The rated drive output power for heavy-duty operation is 3 Horsepower. The enclosure of the 20G21ND8P0JA0NNNNN drive is open. The protection rating of the front side of the drive is IP 20, and the protection rating of the rear side is IP 00. A digital display and keypad are available on the front panel of the drive. However, the 20G21ND8P0JA0NNNNN drive does not include an HMI module. The cooling method for which the 20G21ND8P0JA0NNNNN drive is designed is forced air cooling. This cooling method requires steady airflow around the drive for heat dissipation. Steady or increased airflow can be created by a fan or blower. The minimum rate of airflow recommended for the drive by Allen-Bradley is 50 cubic feet per minute.
