20AD3P4A3AYNANNN

The Allen-Bradley 20AD3P4A3AYNANNN PowerFlex 70 Adjustable Frequency AC Drive is a variable frequency AC drive (VFD) with standard motor control designed for out-of-the-box performance in a variety of industrial and non-industrial processes ranging from simple fan control to pumps applications. To maximize use, this drive provides users with built-in protective features like auto ground fault detection, BUS voltage regulation, programmable temperature control, quick acting current limiting, Inertia Ride-Through (for trip-less operation in the event of power failure), ground fault protection, and line transient spikes in excess of 6000 Volts. The 20AD3P4A3AYNANNN has electrical ratings of 480 Volts AC (3-phase), 3.4 Amps (nominal current), 2.0 Horsepower (output power), a 0.98 displacement power factor, 97.5% efficiency, a 2:1 drive to power ratio and about 200,000 Amps maximum short-circuit current rating. It is programmed for Volts per Hertz motor control by default, and it utilizes a pulse width modulated signal for control. The motor speed is controlled via an adjustable 3-phase voltage output, which is also a function of the output frequency (0 to 400 Hertz), and it offers 0.5% open-loop speed over a 40:1 speed range using slip compensation.

The 20AD3P4A3AYNANNN offers multiple stop modes, depending on application needs, and it has 2 independently programmed acceleration and deceleration times to suit different application needs. It offers Class 10 Electronic motor overload protection (established via the i2t current algorithm), and it has an intermittent overload capability of 115% of the nominal load for 60 seconds. It has an internal dynamic brake transistor (IGBT) which provides cheap but effective breaking, and a CE-certified EMC line filtering which shields the drive from electromagnetic noise. The 20AD3P4A3AYNANNN provide an easy means of start-up, metering, programming, and troubleshooting by using its full numeric featured LCD HMI with multilingual text and a calculator-like number pad for easy data/parameter entry. It has an IP20 rated enclosure that is suitable for simple panel-mounting, and it has an ambient temperature range of 0 to 50 degrees Celsius. The 20AD3P4A3AYNANNN has a net weight of 2.70 kilograms, and it has total mounting dimensions of 122.4 x 225.7 x 179.8 millimeters.
