The 18.5-kilowatts 20AC037A0AYNANC0 from Allen-Bradley is an adjustable-frequency drive. It is a PowerFlex 70 series AC drive which comes in a panel-mounted NEMA/UL Type 1 enclosure and it includes a brake IGBT. The 20AC037A0AYNANC0 includes support for enhanced control. Optional modules for feedback and safe torque-off need to be ordered if these features are required. The output power of the drive is 18.5 kilowatts (25 Horsepower). The output current of the drive is 37 Amps with 3-phase 400 Volts AC input. The D-frame 20AC037A0AYNANC0 has a weight of approximately 20 pounds and the following dimensions: a height of 13.78 inches, a width of 8.66 inches, and a depth of 7.08 inches. A built-in communication slot is not available. Allen-Bradley provides 19 optional communications modules including RS-485 DF1, ControlNet, Modbus/TCP, BACnet, and Ethernet modules. The AC input overvoltage and undervoltage trip values for the 20AC037A0AYNANC0 are 475 Volts AC and 138 Volts AC. The range of input voltages over which the drive can operate is from 342 to 528 Volts AC and the range of input voltages over which the drive can deliver full power at the output is from 400 to 528 Volts AC. The total power dissipated during the drive operation is 404.3 Watts out of which 363.8 Watts are external and 40.5 Watts are internal. The maximum altitude at which the drive can be operated without derating is 3000 feet.
