20AC030A3AYNADC0

The Allen-Bradley 20AC030A3AYNADC0 is a 20 Horsepower AC drive with an integrated DeviceNet interface for network communication. The 20AC030A3AYNADC0 belongs to the PowerFlex 70 product line of adjustable frequency drives. The output power of the 20AC030A3AYNADC0 is 20 Horsepower (15 kilowatts). The drive is designed for 400 Volts AC input. The output current rating of the drive with 3-phase input is 30 Amps. The drive can also operate with single-phase input. However, in this case, the output current can only go up to a maximum of 15 Amps. The maximum altitude at which the drive can operate without the output derating (a reduction of the output current to values below the rated current) is 1000 meters.

The D-frame 20AC030A3AYNADC0 is enclosed in an IP20-rated enclosure. The weight of the panel-mountable drive is approximately 20.4 pounds. In addition to an integrated DeviceNet interface, the drive also includes full-featured HMI and brake IGBT. A brake resistor – if required – needs to be ordered separately. The control mode supported on the 20AC030A3AYNADC0 is enhanced control. Feedback is not available. Because very high voltages and currents are present both at the input and output of the 20AC030A3AYNADC0, the drive should only be handled by people trained in the handling of high-power AC drives. Furthermore, the installation by trained personnel will also ensure that the drive performs as per the specifications without component damage or reduction in the operational lifespan. Bus capacitors on the drive should be allowed to discharge completely before beginning any work on the drive (the voltage can be measured at the +DC terminal of the power terminal block and at the –DC test point).
