20AD027A3NYNANNN

The Allen-Bradley 20AD027A3NYNANNN PowerFlex 70 Adjustable AC Frequency Drive is a variable frequency drive designed to provide out-of-the-box motor control in a variety of applications requiring torque and speed control. This drive incorporates a full-numeric LCD human-machine interface module, which provides multi-language descriptive text for troubleshooting, metering, programming, and start-up, and it comes in a NEMA Type 1 housing designed for standard panel mounting on the factory floor. The 20AD027A3NYNANNN has a 3-phase, 6-pulse input of 480 Volts AC with acceptable input limits of -10% to 10% of the rated input at 47 to 63 Hertz, and it has a current rating of 25 Amps with an output power rating of 15 kilowatts (20 Horsepower). It features fast-acting current limiting and Bus voltage regulation, as well as automatic ground fault detection capability, and in the event of a faulty line, it is designed to provide protection against ground faults and transient voltage spikes using Metal Oxide Varistors across its circuitry.

The 20AD027A3NYNANNN comes with EMC (Integral electromagnetic compatibility) line filtering designed to meet the CE standards, and it also has an internal brake transistor designed for smooth operation. It can be programmed only for standard Volt per Hertz motor control, and it utilizes pulse width modulated signals with a default carrier frequency of 4 kilohertz. The 20AD027A3NYNANNN has an adjustable 3-phase voltage output (0 to the rated motor voltage), controlled by a programmable output frequency range, and it features multiple stop modes, as well as independent acceleration and deceleration times which are programmed independently from 0 to 3600 seconds. It does not have full communication capability, but it can be programmed, monitored, and controlled via the supplied full numeric LCD human-machine interface device with the ability to display descriptive text. The 20AD027A3NYNANNN supports the panel mounting option, and it comes in a NEMA Type 1 rated dust-tight enclosure designed for industrial environments. It has a working temperature range of 0 to 50 degrees Celsius (32 to 122 degrees Fahrenheit), and can be stored at –40 to +70 degrees Celsius (–40 to +158 degrees Fahrenheit). The 20AD027A3NYNANNN has a gross weight of 20 pounds (enclosure included), and a total mounting volume of 8.7 x 13.8 x 7.1 inches.
