20AD3P4A3AYNNDNN

The Allen-Bradley 20AD3P4A3AYNNDNN PowerFlex 70 Adjustable Frequency AC Drive is a digital AC drive with DeviceNet communication capability designed to provide outstanding motor control in a wide range of applications. This drive is programmed for only Volts per Hertz motor control and it is suitable for a range of simple applications from fans to pumps, and like all drive in the series, it is fitted with a standard internal dynamic brake transistor which provides a cost-effective means of switching the excess regenerative energy. The 20AD3P4A3AYNNDNN has a 480 Volts AC (3-phase, 6-pulse) voltage class, with an acceptable input range of 432 to 428 Volts AC, and a current rating of 3.4 Amps. It also has total power output 2.0 Horsepower, with a 0.98 displacement power factor, and an operational efficiency of 97.5%. It has microprocessor excessive temperature monitoring which protects the device against overheating, and its circuitry is lined with removable “metal oxide varistors,” which provide robust protection against ground faults and line transient spikes of up to 6000 Volts.

The 20AD3P4A3AYNNDNN has built-in voltage regulation with wide trip limits, and a fast acting current limit capability, which allows for maximum acceleration and deceleration without tripping. It has the “Inertia Ride-Through” capability, which ensures trip-less operation even in the event of prolonged power failure, and it offers an overload capacity of 150% of the nominal load for 3 seconds. The 20AD3P4A3AYNNDNN offers adjustable 3-phase voltage output that is selectable from 0 to the rated motor voltage, and it offers 0.5% open-loop speed performance by using “Slip Compensation”. It features a cost-effective full numeric LCD human-machine interface module with calculator-like pads and a 7-line by 21-character multilanguage text used for metering, start-ups, configuration, and troubleshooting. It also has an internal DeviceNet communication adapter, which provides an easy means of monitoring, control, programming, and sharing of data with host controllers, and also for seamless integration with most factory processes. The 20AD3P4A3AYNNDNN has an IP20-rated air-tight enclosure designed for both indoor and outdoor use, and it has a rated operating temperature range of 0 to 50 degrees Celsius. The 20AD3P4A3AYNNDNN has an A frame and weighs 6.0 pounds.
