Allen Bradley 20AD3P4A3AYNACC0 Used Surplus

The Allen-Bradley 20AD3P4A3AYNACC0 PowerFlex 70 Adjustable Frequency AC Drive is a digital AC drive from the PowerFlex 70 family of high-performance digital drives that are designed to provide efficient motor control in many applications with demanding speed and torque control requirements. It is designed with a space-saving and cost-saving footprint and is housed within a NEMA Type 1 airtight enclosure that is suitable for conventional panel-mounting around the control cabinet. The 20AD3P4A3AYNACC0 has an operating voltage rating of 480 Volts AC, with 3.4 Amps of drive current rating and a drive power output of 1.5 Kilowatts. It has BUS voltage regulation with a programmable current limiting capability designed for maximum operation without tripping, and it is designed to protect against ground faults and intermittent spikes of up to 6000 Volts using field-removable metal oxide varistors (MOVs). It has an inertia ride-through capability which is designed to provide trip-less operation during a short power loss, and it also has a normal duty overload capacity if 150% for 3 seconds. The 20AD3P4A3AYNACC0 has enhanced motor control options that are selectable between the sensorless vector control and the vector control with FORCE technology designed for high torque and speed control, and it utilizes a PWM signal with a default 4 Kilohertz carrier frequency for control. It has an adjustable 3-phase voltage output determined by the programmable output frequency (0 to 500 Hertz), and it offers 0.1% open-loop speed regulation across 120:1 speed range using "Slip Compensation."

The 20AD3P4A3AYNACC0 offers class 10 motor overload protection established through the i2t current algorithm and it also has individually programmed acceleration and deceleration times. It offers a cheap but effective dynamic brake transistor for switching regenerative energy, and it has a CE standard EMC line filtering which shields the device against electromagnetic noise. The 20AD3P4A3AYNACC0 provide local programming, control, and troubleshooting using its full numeric featured liquid crystal display human-machine interface module, with easy to read text displays and a calculator-like keypad for controlling and entering data. It can also be monitored, controlled, and programmed remotely via a ControlNet communication adapter interface which allows for the easy exchange of data from the host controller, and for seamless integration with factory processes. The 20AD3P4A3AYNACC0 has an operating temperature range of 0 to 50 degrees Celsius, and it can be stored at a –40 to 70 degrees Celsius temperature range. It weighs approximately 6.0 pounds and has total mounting dimensions of 4.2 x 8.8 x 7.1 inches.
