20AC072M3AYNANC0

The Allen-Bradley 20AC072M3AYNANC0 PowerFlex 70 Adjustable Frequency AC Drive is a variable frequency drive with enhanced control that is designed to provide precise motor control in a wide range of applications with accurate torque and speed control. This drive features factory installed dynamic brake transistor (IGBT) without a drive-mounted brake resistor, and it comes in a conformally coated NEMA/UL 1 (IP20) rated enclosure suited for panel mounting and a 5 to 95% non-condensing relative humidity range. The 20AC072M3AYNANC0 has a voltage rating of 400 Volts AC, with 72 Amps of nominal current rating, and it has normal duty and heavy-duty output ratings of 37 and 30 kilowatts, respectively. It has a power factor of 0.98, with an operating efficiency of 97.5%, and it offers 200,000 Amps of maximum fault limit recommended fusible devices and circuit breakers. It offers BUS voltage regulation and a current limiting capability for maximum acceleration and deceleration without tripping, and it comes with built-in protection for ground faults and transient spikes in excess of 6000 Volts.

The 20AC072M3AYNANC0 has programmable temperature monitoring, and it features “Inertia Ride-Through,” which ensures trip-less operation during prolonged power loss. It offers precise control using sinusoidal pulse width modulated signal (PWM), which offers repeatedly accurate control, thereby eliminating guesswork, and it provides an adjustable output voltage, which is a function of the output frequency. The 20AC072M3AYNANC0 offers 0.1% open loop speed regulation across a 120:1 speed range, using slip compensation, and it offers +/-10% torque regulation without an encoder feedback device. It offers high torque control over a wide speed range by using the sensorless vector control method, and it can also be programmed for the field oriented vector control method, which provides out-of-the-box performance without an encoder.  The 20AC072M3AYNANC0 has no network control capability, but it comes with a full numeric LCD human-machine interface module with a multilanguage text display, which provides easy means of control, monitoring, metering, and troubleshooting. It has an operating temperature range of 0 to 50 degrees Celsius, and it is built to withstand 15 g operational shock for 11 milliseconds. The 20AC072M3AYNANC0 is CE, ABS, c-UL-us, and KCC certified, and it weighs approximately 41.0 pounds.
