20G21GC085JA0NNNNN

The Allen-Bradley 20G21GC085JA0NNNNN drive is a PowerFlex 755TS series motor control drive. In addition to AC input, the drive also works with DC input, and so it comes with DC terminals. The DC input voltage rating is 540 Volts DC. The AC input voltage rating is 400 Volts AC and the drive can support 3-phase or 1-phase AC input. Note that the 20G21GC085JA0NNNNN drive’s output derates if it uses 1-phase AC voltage. The drive output also derates if the ambient conditions exceed the limits specified by Allen-Bradley. The rated output of the drive with 3-phase AC input is 85 Amps of current, 45 kilowatts of normal duty output power, and 37 kilowatts of heavy-duty output power. The normal duty peak current rating is 93.5 Amps for 60 seconds and 127.5 Amps for 3 seconds. The heavy-duty peak current rating is 72 Amps for 60 seconds and 108 Amps for 3 seconds. The derated output with single-phase AC input voltage is 22 Amps of current and 43 kilowatts of output.

The Allen-Bradley 20G21GC085JA0NNNNN PowerFlex 755TS series motor control drive can operate at temperatures between -20 degrees Celsius and 40 degrees Celsius. The altitude limits of the drive depend on voltage. The altitude limit for Overvoltage Category II applications is 9000 meters with a center grounded system configuration, and it is 4800 meters for Overvoltage Category III applications with a center grounded system configuration. The storage temperature range for the 20G21GC085JA0NNNNN drive is -40 to 70 degrees Celsius. The 20G21GC085JA0NNNNN drive does not include an HMI module. The drive is available in an NEMA enclosure with an IP 54 protection rating. The drive includes a heatsink for improved heat dissipation. The total heat dissipation rating of the 20G21GC085JA0NNNNN drive is 871 Watts. The minimum spacing recommendations above and below the mounted drive is 76.2 millimeters. The approximate weight of the drive is 21 kilograms.
