Allen Bradley 20AD040F0AYNANC0 PowerFlex 70 AC Drive 40 A at 30 Hp 20A - Used Surplus

The Allen-Bradley 20AD040F0AYNANC0 PowerFlex 70 Adjustable Frequency AC Drive is part of the PowerFlex 70 product line that is used for controlling 3-phase induction motors in processes involving speed and torque control. It has an operational voltage of 480V AC, with a voltage tolerance of -10% minimum and +10% maximum at a 47 to 63Hz input frequency tolerance range, and it has a 0.98 operational power factor, with 97.5% drive efficiency. It has both heavy-duty and normal-duty ratings, and it has 40A and 22kW (30HP) normal duty output ratings, and 18.5kW (25HP) heavy-duty output rating. The 20AD040F0AYNANC0 offers AC input overvoltage trips and under voltage trips of 570V and 280V, respectively, with a microprocessor-controlled over temperature trip at the heatsink, and it has programmable overcurrent trips with limits between 20% and 160%. It provides a line transient protection of as much as 6000V, with phase-to-phase plus phase-to-ground protection at the drive’s output, using a Metal Oxide Varistor (MOV), and it can ride through 15ms power loss at full load.

The 20AD040F0AYNANC0 uses a sine-coded pulse width modulated signal with a programmable carrier frequency range of 2 to 12 KHz for speed control, and its output voltage range is 0 to the rated motor voltage, determined by a 0 to 400Hz programmable output frequency range. The kit employs the Sensorless Vector control with full tuning and the Standard Volt per Hertz control with full custom capability for motor control, and its Digital and Analog control inputs have an accuracy within ±0.01%, and ±0.4% of the maximum output frequency. The 20AD040F0AYNANC0 offers an open ±0.5% speed regulation across a 40: 1-speed range in an open-loop with slip compensation, and it features two independently programmable Acceleration/Deceleration times, which is separately programmable from 0 to 3600s in 0.1s increments. The 20AD040F0AYNANC0 provides a 110% overload capability for 1 minute, and a 150% overload capability for up to 3s, and it also offers Class 10 motor protection with speed-sensitive responses. It has an operating temperature range of 32 to 122°F, at 5 to 95% humidity, and a storage temperature of -40 to 158°F. It supports the Flange Mount option, and it is enclosed in an IP20 (NEMA Type 1) rated enclosure. It has an approximate weight of 9.25kg, with shipping dimensions of 248.4mm x 350.0mm x 178.6mm, and it UL, c-UL-us, and CE certified.
