20AD3P4A3AYYACNN

The Allen-Bradley 20AD3P4A3AYYACNN Adjustable Frequency AC Drive is a digitally-controlled Variable Frequency Drive (VFD) from the PowerFlex 70 series of high-performance AC drives designed to provide out-of-the-box performance in many applications. This drive offers speed and torque control solutions to a wide range of applications ranging from fans to simple pumps, and it offers exceptional speed control using “slip compensation”, which delivers 0.5% open-loop speed control, thereby eliminating the need for feedback devices on this application. The 20AD3P4A3AYYACNN has a voltage class of 480 Volts AC, with -/+10% acceptable input range, and an input current rating of 3.4 Amps. It has a drive to motor power ratio of 2 to 1, and a displacement power factor of 0.98 across the entire speed range. It has 1.5 Kilowatts total power output at 200,000 Amps maximum fault limit current, based on specified circuit breakers and fuses. The 20AD3P4A3AYYACNN has fast-acting current limiting and BUS voltage regulation which ensures optimized operation and it also features programmable excessive temperature control at the heatsink. It features 15 milliseconds of inertia ride-thru by using rotating energy from high-inertia, friction-free loads, and it provides protection against ground faults and intermittent line transient spikes using field-removable metal oxide varistors.

The 20AD3P4A3AYYACNN is factory programmed for a Volts per Hertz (V/H) motor control option, and it uses sinusoidal pulse width modulated control signal with 4 Kilohertz default carrier frequency for control. The 20AD3P4A3AYYACNN has selectable output voltage, regulated by a programmable output frequency range of 0 to 400 Hertz, and it offers 2 independently programmed acceleration and deceleration times, in addition to multiple stop options.  The 20AD3P4A3AYYACNN is fitted with the integral dynamic brake transistor and the optional internal dynamic brake resistor which provides a very large braking torque over a short period for optimal operation, and it also has an EMC filtering option with the European CE standard. It comes with NEMA Type 1 enclosure built to be dust and air-tight, and it has an operating ambient temperature limit 50 degrees Celsius. The 20AD3P4A3AYYACNN is a frame A drive with 2.71 kilograms of net shipping weight and with total shipping dimensions of 122.4 x 225.7 x 179.8 millimeters.
