20AD3P4A3AYNADG0

The Allen-Bradley 20AD3P4A3AYNADG0 Adjustable Frequency AC Drive is a communication enabled digital AC drive and a member of the PowerFlex 70 family of enhanced performance drives, built for excellent motor control solutions in many applications with precise torque and speed control needs. This drive features enhanced motor control options that are programmable from the Vector control and the Sensorless Vector control (SVC), and a Safe Torque-Off (STO) circuit, an integrated safety circuit which ensures that the connected motor is not acted on by torque-generating energy, thus preventing unintentional starting. The 20AD3P4A3AYNADG0 has a nominal drive rating of 480 Volts AC (6-pulse), with a 432 Volts AC to 528 Volts AC acceptable input range at 47 to 63 Hertz line input frequency range, and an operating current of 3.4 Amps. This drive has a 2.0 Horsepower power rating, with a 0.98 power displacement factor, and 97.5% efficiency with a maximum load. It has a recommended 2:1 drive/motor ratio, and it can deliver up to 200,000 Amps of the maximum fault current limit using specified fusible devices and circuit breakers.

The 20AD3P4A3AYNADG0 has a built-in voltage regulation capability with current limiting action which ensures maximum acceleration and deceleration without tripping and it has programmable temperature monitoring, thus preventing damage from overheating. It has Inertia Ride-Through, a function which allows for trip-less operation through 15 milliseconds of a power outage, and it provides protection against line transient spikes in excess of 6000 Volts, and ground fault trips on the output by using Metal Oxide Varistors (MOVs). It utilizes pulse width modulated (PWM) control with 4 Kilohertz carrier frequency, and it has an adjustable output voltage controlled by 0 to 500 Hertz programmable output frequency. It offers 0.1% open-loop speed control over a 120:1 speed range, using slip compensation, and it also offers 2 independently programmed acceleration/deceleration times for optimized control. The 20AD3P4A3AYNADG0 has DeviceNet communication capability which provides for easy integration into the factory process, and it provides control, programming, and transmission of data with host controllers. The 20AD3P4A3AYNADG0 has an LCD HMI with full numeric keypads for data entry, and for start-up, control, configuration, and troubleshooting. The 20AD3P4A3AYNADG0 has a 0 to 50 degrees Celsius operating temperature range, and it is shipped with a NEMA/UL Type 1 enclosure suitable for conventional panel mounting. The 20AD3P4A3AYNADG0 has an average weight of 2.70 kilograms, and it has total dimensions of 122.4 x 226.0 x 180.0 millimeters (H x W x D).
