20G21GC043JA0NNNNN

The Allen-Bradley 20G21GC043JA0NNNNN PowerFlex 755TS series motor control drive is a digital drive. Its rated output current is 43 Amps. The drive can operate in normal duty and heavy-duty modes. The rated power output for the normal duty mode is 22 kilowatts. The rated power output for heavy-duty mode is 18.5 kilowatts. Allen-Bradley has designed the drive for both AC and DC input. The 20G21GC043JA0NNNNN drive comes with DC terminals and it supports AC input with precharge. The frame size of the drive is Size 3. The enclosure is a NEMA/UL Type 12 enclosure. The protection rating of the drive is IP 54. This rating means that the drive is protected against dust and against water sprays. If the operators want to improve the drive’s protection, they can mount the drive inside a cabinet with a higher level of ingress protection than IP 54. The 20G21GC043JA0NNNNN drive housing provides it with a standard level of protection against any corrosive gasses that may be present in the operating environment.

The Allen-Bradley 20G21GC043JA0NNNNN PowerFlex 755TS series motor control drive supports connection to single-phase AC power supplies as well as 3-phase AC power supplies. However, the drive output derates with single-phase AC voltage. The drive output also derates if the operators use it in environmental conditions that differ from those recommended by Allen-Bradley. The specified ambient conditions for the 20G21GC043JA0NNNNN drive include an operating temperature range of -4 to 122 degrees Fahrenheit and 0 to 1000 meters of operating elevation. The required air flow around the drive for proper heat dissipation is 80 cubic feet per minute. The 20G21GC043JA0NNNNN drive does not feature a built-in HMI. However, the drive supports integrated Gigabit Ethernet communication ports. The presence of these dual Ethernet ports allows the 20G21GC043JA0NNNNN drive to be used in multiple network topologies.
