20AD040A0AYNANNN

The Allen-Bradley 20AD040A0AYNANNN AC Digital Drive is an adjustable frequency drive from the PowerFlex 70 series of high-performance AC drives designed to provide motor control solutions in a wide range of motion control applications. This drive features the standard Volts per Hertz (V/H) control method that is suitable for simple applications like pumps and fans, and it also features “Slip Compensation,” a function which automatically calculates and delivers 0.5% open-loop speed regulation across a wider range of speed, thereby improving speed accuracy. The 20AD040A0AYNANNN has a standard drive rating of 22 kilowatts (30 Horsepower) at 480 Volts AC input, and it has a nominal current (load) rating of 40 Amps. This drive has an outstanding power factor of 0.95 and an operational efficiency rating of 97.5%, and with the use of specified circuit breakers and fuses, it can deliver a maximum short-circuit rating of 200,000 Amps (Symmetrical).

Like every PowerFlex 70 AC Drive, the 20AD040A0AYNANNN comes with an integral dynamic transistor brake designed to provide low-cost but effective motor braking and it also has CE standard EMC line filtering for enhanced operation. It has BUS voltage regulation and a current limiting capacity designed for maximum deceleration and acceleration without tripping, and it also has a microprocessor-monitored excessive temperature control that is designed to prevent damage from excess heat. For control, the 20AD040A0AYNANNN utilizes Pulse Width Modulated control with a 4 KiloHertz default carrier frequency, and it has a programmable output frequency range from 0 to 400 Hertz which determines the output voltage. This drive offers 2 independently programmed acceleration and deceleration times, and depending on the application requirements, the users can program the drive for various stop options. The 20AD040A0AYNANNN has a NEMA Type 1 housing and an operating temperature range of 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit). The 20AD040A0AYNANNN has a net weight of 9.25 kilograms (20.4 pounds) and total dimensions of 219.9 x 350.0 x 179.8 millimeters (8.66 x 13.78 x 7.08 inches).
