20AC037A3AYNANC0

The 25-Horsepower 20AC037A3AYNANC0 from Allen-Bradley is a drive designed for the control of motors in applications ranging from fans to extruders. It is part of the PowerFlex 70 series which fulfills requirements for reliability and simplicity in a compact package featuring power and control options. Operating at nominal input of 400 Volts AC, the 20AC037A3AYNANC0 offers 25 Horsepower at the drive output. With 3-phase input voltage, the drive is able to deliver 37 Amps continuous current at the drive output. The drive also operates with single-phase input. However, in this case, the output current derates and it can only go up to a maximum of 18.5 Amps.

Available in a D-frame enclosure, the 20AC037A3AYNANC0 weighs 20.4 pounds. The panel-mounted enclosure measures 350.0 x 219 x 179 millimeters. To aid in keeping the ambient temperature around the drive between 0 and 50 degrees Celsius, Allen-Bradley recommends 76 millimeters of vertical spacing. A cooling fan is also provided which operates when the drive is powered on and is in the “Run” state. A drive-mounted HMI on the 20AC037A3AYNANC0 includes both an LCD and a keypad. Additional features include a brake IGBT and support for enhanced control. An optional 5V/12V encoder module needs to be ordered from Allen-Bradley if feedback is required. Optional modules for the brake resistor and communication slot also need to be ordered if they are required because the drive does not include these features. Modbus/TCP, LonWorks, Ethernet, BACnet, and RS-485 are some of the communications adapters available as options from Allen-Bradley.
