Allen-Bradley 20F11ND052AA0NNNNN

This AC drive constructed by Allen Bradley/Rockwell Automation has a horsepower ND output rating of 40 Horsepower. Furthermore, this Allen-Bradley AC Drive is contained in an IP20/IP00 Open enclosure. Additionally, this AC drive comes with power requirements of 480 Volts AC and has a blank HIM cover in place of the display but an HIM can be installed. In addition, this PowerFlex 750 (PF753) adjustable frequency drive has an amperage rating of 52A. Furthermore, this VAC drive has a dynamic braking transistor included for braking applications.

The 20F11ND0052AA0NNNNN is an adjustable frequency AC drive that is part of the PowerFlex 753 adjustable Frequency AC drives. This drive is a 480VAC, 3-Phase rated drive with output current of 52 Amperes and power of 40 HP at Normal duty operation; 40 Amperes and 30 HP for heavy duty operation. Additionally, this drive delivers 57.2 Amperes for 1 min; and 78 Amperes for 3 seconds in normal duty operation and 60 Amperes for 1 min and 78 Amperes for 3 seconds in heavy duty operation.

The 20F11ND0052AA0NNNNN has an AC input overvoltage trip of 576V AC and AC input undervoltage trip 300V AC while the Bus Overvoltage trip is 815V DC. Being a Frame 5 drive, the 20F11ND0052AA0NNNNN has Bus undervoltage shutoff of 400 VDC. The nominal bus voltage of this drive is 648V DC. Other built-in electrical protection to this drive are Ground fault trip which is triggered by Phase-to-ground connection on drive output and Short circuit trip of Phase-to-phase on drive output.

The output frequency of the 20F11ND0052AA0NNNNN are 0…325 Hz at 2 kHz carrier and 0…590 Hz at 4 kHz carrier configuration. The drive’s available stop modes are Ramp, Coast, DC-Brake, Ramp-to-Hold, Fast Braking, and Current Limit Stop while Acceleration and deceleration settings are Two independently programmable accel and decel times. Each time can be programmed from 0…3600 seconds in 0.1 second increments (0 to motor nameplate speed).

The 20F11ND052AA0NNNNN adjustable frequency AC drive operates with a voltage rating of 480 Volts AC and 650 Volts DC, with an ND rating of 52 Amps and 40 Hp. It has an AC input with a precharge PCB that includes DC terminals, filters, and an internal transistor, with its jumper removed. The 20F11ND052AA0NNNNN adjustable frequency AC drive is designed afor installation to an enclosure that can be used exclusively for indoor environments, specifically an IP20 or an IP00 enclosure. This kind of enclosure protects this AC drive from particles and solid objects over 12 millimeters. This enclosure also impedes that operators have direct contact with important and fragile parts of the drive; since these drives are highly electrical, this enclosure protects both the drive and operator from possible damages. With this enclosure, the drive can withstand an ambient air temperature range from 0 to 50 degrees Celsius and a relative humidity of 95%, and it can operate without derating at an altitude of 1000 meters. The 20F11ND052AA0NNNNN adjustable frequency AC drive is a normal duty rated drive, with this qualification the drive is able to offer capacities of 100% when it comes to continuous torque, 110% of current for one minute and 150% of current for 3 seconds.
