20G21ND3P4JA0NNNNN

The Allen-Bradley 20G21ND3P4JA0NNNNN motor control drive is a 2 Horsepower-rated motor control drive. It is part of the Allen-Bradley PowerFlex 755TS series of advanced drives. The 20G21ND3P4JA0NNNNN drive supports patented Allen-Bradley TotalForce motor control technology. It also supports several other features including option cards for communication, I/O, and safety features, dual-Ethernet connectivity through 2 Ethernet ports, and predictive maintenance that helps to improve productivity and reduce downtime. The 20G21ND3P4JA0NNNNN drive is designed for connection to AC mains supplies. It supports both 3-phase and single-phase AC input. The nominal input line voltage rating is 480 Volts AC. The nominal motor voltage rating is 460 Volts AC. The 20G21ND3P4JA0NNNNN drive’s full AC power range is 460 to 528 Volts AC, and its operating voltage range is 342 to 528 Volts AC.

The Allen-Bradley 20G21ND3P4JA0NNNNN PowerFlex 755TS series motor control drive supports input protection and it trips at the preset high and low voltage thresholds to protect itself. The high-voltage input trip threshold is 576 Volts AC, and the low-voltage input trip threshold is 300 Volts AC. At a full load, the nominal bus voltage rating is 648 Volts DC. The drive is also programmed to trip if the DC bus voltage reaches the high or low bus voltage threshold values. The high-voltage threshold for bus voltage is 815 Volts DC, and the low-voltage threshold for bus voltage is 200 Volts DC. The 20G21ND3P4JA0NNNNN drive relies on forced air cooling to avoid overheating. The operating temperature range for the full rated output is -4 to 122 degrees Fahrenheit. The operating temperature range for derated output is from 122 to 140 degrees Fahrenheit. Allen Bradley does not recommend using the drive at temperatures above 140 degrees Fahrenheit. The continuous current output rating is 3.4 Amps. The 20G21ND3P4JA0NNNNN drive does not feature an HMI module.
