20DD077A3ENNANNNN

The Allen-Bradley 20DD077A3ENNANNNN is an adjustable frequency AC drive designed to implement perfect control of inductive three-phase motors. This is a 480 Volts AC drive that can deliver up to 60 Horsepower and 77 Amps to the motor. It has integrated HMI with a backlit LCD and with the full numeric keyboard. The device is delivered with the quick setup guide in English in a booklet and on a CD. The Allen-Bradley 20DD077A3ENNANNNN belongs to the PowerFlex 700S series of adjustable frequency AC drives. At the output side, as the voltage is changed, the frequency can vary from 0 to 300 Hertz.

At the output side, this AC drive generates a sine-coded PWM with the programmable carrier frequency. The efficiency of the drive is 97.5% at the rated current. This module is enclosed with an IP20 (NEMA Type 1) enclosure type. The 20DD077A3ENNANNNN has independently programmable acceleration and deceleration times. These times can be programmed in a 0 to 6553.5 seconds range (with 0.1-second increments). The dimensions of the Allen-Bradley 20DD077A3ENNANNNN housing are 8.69 inches (220.8 millimeters) x 29.9 inches (758.8 millimeters) x 7.94 inches (201.8 millimeters). The item weighs around 28 kilograms (62 pounds). The terminal block is situated in the bottom part of the drive and all connectors can be pulled out for quick wire installation. Users can store this device at -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit) and operate it at 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit).
