20AD040A0AYNANC0

The 20AD040A0AYNANC0 PowerFlex 70 Adjustable Frequency AC Drive is a variable frequency drive by Allen-Bradley, that provides microprocessor and digital motor control in a variety of applications with speed control needs. This drive comes in a compact and flexible package for easy setup, and it features current limit, voltage regulation, and PI control which completely remove the need for a secondary process loop controller. It has 480 Volts AC 3-phase, 6-pulse input power, with a drive rating of 40 Amps, 22 kW (30 Horsepower), and it has an input range of -10% to +10% of the rated input at 47 to 63 Hertz. The 20AD040A0AYNANC0 has a displacement power factor of 0.98, with a rated efficiency of 97.5%, and it has a short-circuit rating of 200,000 Amps. It provides overvoltage and under voltage trips, with a current limit trip of 20% to 160% of the rated current, and it has microprocessor over temperature control at the heatsink. This drive is designed to have a maximum power ride-through time of 15 milliseconds, with 2 seconds of the standard logic ride through time, and it also confers transient line protection of up to 6000 Volts and ground fault protection at the output. The 20AD040A0AYNANC0 provides enhanced motor control and I/O, selectable between the sensorless vector control and the vector control, and it utilizes sine coded Pulse Width Modulation with programmable 4 KiloHertz carrier frequency for control.

The 20AD040A0AYNANC0 has a programmable 0 to 400 Hertz output frequency range, with a selectable voltage range of 0 Volts to the rated motor voltage output, and it offers 0.5% frequency control and 0.1% speed regulation across 40:1 and 120:1-speed ranges, without an encoder feedback device. The 20AD040A0AYNANC0 provides Class 10 electronic motor overload protection, with an overload capability of 115% for 60 seconds, and it has 2 separate acceleration and deceleration times. This drive is a panel mounted device with IP20 rated enclosure and a flange-like heatsink with mounting holes. It supports EC filtering and a transistor braking system, but it does not support the safe torque OFF option. It has a functional temperature range of 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit) at 5% to 95% non-condensing relative humidity range, and it has a storage temperature range of -40 to 70 degrees Celsius (-40 to 158 degrees Fahrenheit). The 20AD040A0AYNANC0 has a net weight of 9.25 kilograms, with shipping dimensions of 219.9 x 350.0 x 179.8 millimeters, and it is cUL-us, CE, RCM, ABS, and EAC certified.
