20G21ND077JA0NNNNN

The Allen-Bradley 20G21ND077JA0NNNNN PowerFlex 755TS series drive is a motor control drive designed for industrial motor control applications. It supports AC and DC input. The DC input rating is 650 Volts DC and the drive includes DC terminals. The 20G21ND077JA0NNNNN drive also supports 3-phase AC systems and its AC input rating is 480 Volts AC. The drive can support single-phase AC input too, but only with derated output. The full rated continuous current rating is 77 Amps, the normal duty output power rating is 60 Horsepower, and the heavy-duty output power rating is 50 Horsepower. The peak output current is 84.7 Amps for 60 seconds and 115.5 Amps for 3 seconds. Single-phase output ratings include 30 Horsepower of output power, 40 Amps of output current, and 75 Amps input current. The frame size of the drive is Size 5. Its enclosure is open with IP 20 rating for the front and IP 00 rating in the back. The housing of the drive provides standard protection from corrosive gasses.

Allen-Bradley has designed the 20G21ND077JA0NNNNN PowerFlex 755TS series motor control drive for forced air cooling. The recommended minimum airflow for appropriate heat dissipation is 520 cubic feet per minute. The operating temperature range for the 20G21ND077JA0NNNNN drive is from -20 to 50 degrees Celsius. The maximum permitted ambient operating temperature with output derating is 60 degrees Celsius or 140 degrees Fahrenheit. Note that the internal drive temperature is much higher than the ambient temperature. To prevent device malfunctioning, it is essential to maintain the ambient operating temperatures within the range specified by the manufacturer. The drive does not include an HMI module. Only trained professionals should handle the 20G21ND077JA0NNNNN drive, associated accessories, equipment, and machinery.
