20AC072A0NYNAEC0

The 20AC072A0NYNAEC0 variable speed drive belongs to the PowerFlex 70 series. This series has been manufactured, designed, and distributed by Allen-Bradley. The Allen-Bradley 20AC072A0NYNAEC0 variable speed drive operates with a 3-phase voltage of 400 Volts AC and an amperage rating of 72 Amps. It can be derated in order to operate with single-phase applications. The Allen-Bradley 20AC072A0NYNAEC0 variable speed drive modifies the input voltage and frequency of an electromechanical motor in order to control its torque and speed. It can be programmed to do these modifications manually or automatic. It does not include any human-machine interface but one can be added in order to improve the performance of the drive.

Through a human-machine interface, the drive can be fully started and programmed and the operators have advantages like checking the variables whenever they feel they need to do it and modify, add, and change the whole functioning. Faults are also shown through this human-machine interface. The Allen-Bradley 20AC072A0NYNAEC0 variable speed drive provides a compact design with the use of a NEMA Type 1 enclosure that enables it to be panel-mounted without any loose connections all over the place. This enclosure protects these connections and avoids the contact between them and operators. By being open, it enables the drive to withstand higher temperatures than regular enclosures. The maximum temperature is 50 degrees Celsius. It is recommended to install and store the drive in a clean and dry environment. The Allen-Bradley 20AC072A0NYNAEC0 variable speed drive is not filtered, it provides an Ethernet connection and it has an enhanced control I/O.
