20AD3P4A3AYNNEG0

The Allen-Bradley 20AD3P4A3AYNNEG0 PowerFlex 70 Adjustable Frequency AC Drive is an enhanced digital AC Drive from the Powerflex 70 family of programmable drives that are designed to provide efficient control in a wide range of applications requiring speed and torque control. The drive features a cost-effective dynamic brake transistor for switching regenerative energy, and it offers maximum acceleration and deceleration without tripping via built-in voltage regulation and current limiting capability. The 20AD3P4A3AYNNEG0 has a 6-pulse, 3-phase line voltage class of 480 Volts AC, with 3.4 Amps of nominal current rating, and a total output power of 1.5 Kilowatts. It has a line input range of -/+10% at 63 Hertz, and like all PowerFlex 70 drives, it has a 0.98 displacement power factor across the entire speed range. Using specific circuit breakers and fusible devices, the 20AD3P4A3AYNNEG0 can deliver 200,000 Amps of maximum short-circuit current rating, and it has a recommended power ratio of 2 to 1 (drive to motor). For optimized operation, all PowerFlex 70 drives are designed with built-in protective features like fast-acting programmable current limiting, auto BUS voltage regulation, excessive temperature control, milliseconds-long inertia ride-thru, ground fault protection, intermittent line spike protection, and Class 10 motor overload protection.

The 20AD3P4A3AYNNEG0 has an enhanced control option, and it is embedded with the Safe Torque-Off (STO) circuit, which halts the torque-generating energy from acting on motors, therefore preventing unintentional starting and tripping. It provides low-cost braking by using an internal dynamic brake transistor, which is supplied as standard with all PowerFlex 70 drives, and by using slip compensation, the 20AD3P4A3AYNNEG0 offers 0.1% open-loop speed regulation over a 120:1 speed range, thereby eliminating cost from feedback devices in some applications. It is fitted with a full numeric LCD human-machine interface module, which features a 7-line by 21-character multi-language screen and keypads for control and it is used for easy metering, start-up, programming, and troubleshooting. The 20AD3P4A3AYNNEG0 is an Ethernet/IP enabled drive, with an internal Ethernet/IP communication adapter which provides easy and remote control, programming, access, transfer of data, and seamless integration with factory processes. It designed for use within a non-condensing non-corrosive 5 to 95% relative humidity condition, and it has an ambient operating temperature range of 0 to 50 degrees Celsius within an IP20 rated housing. The 20AD3P4A3AYNNEG0 has an average shipping weight of 6.0 pounds, and total mounting dimensions of 4.8 x 8.9 x 7.1 inches.
