20AD3P4A3AYNNNC02

The Allen-Bradley 20AD3P4A3AYNNNC02 PowerFlex 70 Adjustable Frequency AC Drive is an AC drive with enhanced digital control designed to provide a high degree of motor control in a wide range of simple and complex non-industrial and industrial applications requiring speed and torque control. This drive features enhanced motor control without a safe torque-off option, but it features a 12 Volts DC dual incremental encoder option which helps to deliver 0.001% open-loop speed regulation, thus providing precise speed control over a load. The 20AD3P4A3AYNNNC02 has an operating voltage rating of 480 Volts AC (3-phase, 6-pulse), with 3.4 Amps of nominal current rating, and an output power rating of 2.0 Horsepower. It has an input range of -10% to +10% of the rated nominal input, and it can provide a branch circuit protection of up to 200,000 Amps with the use of specified circuit breakers and fusible devices. The 20AD3P4A3AYNNNC02 has an inertia ride-through function which provides continuous faultless ride-through during a short power loss and it also has a slip compensation function which delivers 0.1% speed regulation over a 120:1 speed range in some applications, thereby eliminating the need for an encoder feedback device. It features BUS voltage regulation and current limiting action, which allows for maximum acceleration and deceleration without tripping, and it has built-in protection from overheating, phase-to-phase faults, and any intermittent spikes in excess of 6000 Volts.

The 20AD3P4A3AYNNNC02 features an enhanced motor control option without an embedded safe torque-off circuit, but it can be programmed for either the Sensorless Vector control or the Vector control with patented FORCE Technology, to accommodate a wide range of applications. This drive has a 3-phase output voltage adjustable from 0 to the rated motor voltage, and it offers 2 independently programmed acceleration and deceleration times in addition to multiple programmable stop modes. The 20AD3P4A3AYNNNC02 has a liquid crystal display HMI with full numeric keypad and multilingual display text for start-up, programming, metering, and troubleshooting. It has a NEMA indoor/outdoor rated air-tight enclosure designed for 5 to 95% non-condensing humidity and a non-corrosive industrial environment and a temperature range of 0 to 50 degrees Celsius. The 20AD3P4A3AYNNNC02 is CE, RCM, KCC, c-UL-us, and ABS certified, and it has total dimensions of 122.4 x 225.7 x 179.8 millimeters.
