Allen Bradley 20AD5P0A1AYNNNNN Used Surplus

The 20AD5P0A1AYNNNNN PowerFlex 70 Adjustable Frequency AC Drive by Allen-Bradley is a digitally controlled AC Drive from the PowerFlex 70 family of enhanced drives that are designed to provide out-of-the-box performance in a wide range of applications. This drive offers slip compensation, a feature which allows for accurate speed control on loads without a feedback device, and it is capable of delivering 0.5% speed regulation across a 40:1 speed ratio. The 20AD5P0A1AYNNNNN has a drive output power rating of 3.0 Horsepower, and a nominal load rating of 5 Amps at 480 Volts AC input. It has a power factor of 0.98 and an operational efficiency of 97.5% at nominal load. The 20AD5P0A1AYNNNNN features fast acting current limiting that is programmable from 20 to 160% of the nominal rating, and it also features BUS voltage regulation for maximum acceleration and deceleration without tripping. It has excessive temperature control, which digitally monitors the drive temperature, thus preventing damage resulting from an excessive temperature, and it also has an automatic ground fault detection capability. 

The 20AD5P0A1AYNNNNN features an internal dynamic brake transistor which provides a cheap means of switching regenerative energy, but it does not offer electromagnetic compatibility (EMC) line filtering. It is programmed for only Volt per Hertz control, and it utilizes a sinusoidal Pulse Width Modulated (PWM) signal for control. It offers users multiple stop modes, and the users can independently program the acceleration and deceleration times. The 20AD5P0A1AYNNNNN features an LED human-machine interface module with full digital control and multilingual text display and a simple 7 lines by 21 characters backlit display for the start-up, metering, programming, and troubleshooting data. The 20AD5P0A1AYNNNNN has an IP20 airtight and dust-tight industrial enclosure that is designed for conventional cabinet panel mounting, and this enclosure supports Zero Stacking with a 50 degrees Celsius maximum operating ambient temperature. The 20AD5P0A1AYNNNNN has a gross shipping weight of 3.60 kilograms, and aggregate mounting dimensions of 172.0 x 235.0 x 170.0 millimeters.
