20G21RD8P0JA0NNNNN

The Allen-Bradley 20G21RD8P0JA0NNNNN motor control drive is a digital variable frequency drive. It is part of the Allen-Bradley PowerFlex 755TS product line. The drive is available in an open NEMA/UL enclosure. The ingress protection rating of the front panel is IP 20 and the ingress protection rating of the back panel is IP 00. The 20G21RD8P0JA0NNNNN drive’s output ratings depend on a number of factors that include the drive’s input voltage and ambient conditions including temperature, humidity, and elevation. The rated output current is 8 Amps, and the rated output power is 5 Horsepower normal duty and 3 Horsepower for heavy-duty. Full rated drive output power requires 3-phase AC input voltage between 460 and 528 Volts AC. The nominal AC input voltage rating of the 20G21RD8P0JA0NNNNN drive is 480 Volts AC while the nominal DC input voltage rating is 650 Volts DC. With single-phase AC input voltage, the output power derates to 2.5 Horsepower and the output current derates to 4 Amps.

The Allen-Bradley 20G21RD8P0JA0NNNNN PowerFlex 755TS series motor control drive’s output also derates at ambient temperatures that are between 50 and 60 degrees Celsius. The recommended operating temperature range is -20 to 50 degrees Celsius for safe operation at full output. For drives with standard corrosion protection like the 20G21RD8P0JA0NNNNN drive, the tolerable ambient relative humidity range is from 5 to 95% without condensation. The frame size of the drive is Size 1. Allen-Bradley recommends 50 CFM of minimum airflow for proper heat dissipation. Additionally, 76.2 millimeters of space above and below the drive are recommended for good ventilation. The 20G21RD8P0JA0NNNNN drive does not feature an HMI. However, a display screen and keypad on the front panel support drive monitoring and the basic configuration of drive parameters. The 20G21RD8P0JA0NNNNN drive should be installed by trained professionals to avoid wiring errors.
