The Allen-Bradley 20AD027A3AYNACG0 is a PowerFlex 70 AC drive from Rockwell's PowerFlex family. At 480 V AC 3-phase input it is rated 20 HP (15 kW) normal duty and 15 HP heavy duty, with 27 A continuous output current, 33 A for 60 s and 44 A for 3 s. It is a panel-mount IP20, NEMA/UL Type 1 drive in frame D, rated for 0…50 °C surrounding air without derating. Conformal coating is standard. It comes with a full numeric LCD HIM with a 7-line x 21-character backlit display. It has an internal brake IGBT but no internal brake resistor, and an integral EMC filter. It includes an internal ControlNet (coax) communication adapter. It has enhanced control with DriveGuard Safe Torque Off, which meets EN ISO 13849-1 Category 3. Motor control is volts per hertz, sensorless vector or vector control with FORCE Technology, with a 0…500 Hz output frequency range, 110% overload for up to 1 minute or 150% for up to 3 seconds, and Class 10 motor overload protection.
