Allen Bradley 20AD040A0AYNADNN Used Surplus

The Allen-Bradley 20AD040A0AYNADNN PowerFlex 70 Adjustable Frequency AC Drive is a variable frequency drive designed to provide out-of-the-box performance in a variety of applications ranging from simple to complex industrial processes. It is compactly designed to save operation costs, and it is enclosed in an airtight NEMA Type 1 enclosure with support for Zero Stacking (placing 2 drives side by side). The 20AD040A0AYNADNN has 480 Volts AC drive operating voltage, with 40 Amps of nominal line load, and it has an output rating of 30 Horsepower. It has a recommended 2:1 drive to power ratio by design, and it offers 0.98 displacement power factor and an operational efficiency of 97.5% at the full nominal load. It has BUS voltage regulation with trip limits of 570 and 280 Volts AC, and it also has fast-acting current limiting which allows for maximum operation without tripping. This drive offers protection against a ground fault by using field removable MOVs (metal oxide varistors), and it has a maximum short-circuit rating of 200,000 Amps utilizing fusible devices and circuit breakers. It has an overload limit of 110% of the nominal rating for 1 minute, and it can provide Class 10 motor overload protection by utilizing the it2 algorithm.

The 20AD040A0AYNADNN features standard motor control (Volt per Hertz control), and it utilizes a sinusoidal pulse width modulated signal for control. Its output voltage is adjustable from 0 Volts to the rated motor voltage, and it has an output control frequency that is programmable from 0 to 400 Hertz. It utilizes slip compensation, a function which allows for accurate speed control over a line load, and this helps to deliver 0.5% open loop speed regulation without a feedback device. The 20AD040A0AYNADNN has an internal dynamic brake transistor, which provides low-cost means of braking and it is designed with CE certified line filtering for optimal operation. It is also designed with a DeviceNet Communication adapter option which allows for the exchange of data, control, and monitoring over the DeviceNet network, and also for easy integration into the factory machine systems. The 20AD040A0AYNADNN has an IP20 rated enclosure, and it is designed to operate within a 0 to 50 degrees Celsius temperature range without de-rating. The 20AD040A0AYNADNN is CE, c-UL-us, RCM, and ABS certified, and it has a net shipping weight of 20.4 pounds and approximate dimensions of 8.66 x 13.78 x 7.08 inches.
