20AD027A3NYNANC0

The Allen-Bradley 20AD027A3NYNANC0 Adjustable Frequency AC Drive is a digital variable frequency drive (VFD) in the Powerflex 70 class of global solution drives that are designed to provide out-of-the-box motor control in a wide range of applications with torque and speed control needs. This drive, like all others in the series, features fast-acting current limiting and BUS voltage regulation for excellent operation without tripping, and it is also designed with internal dynamic brake transistor for low-cost but effective braking. The 20AD027A3NYNANC0 has a 6-pulse, 3-phase input voltage of 480 Volts AC, with a minimum and maximum acceptable range of -10%/+10%, and it has an output power rating of 15 kilowatts. It has a continuous current rating of 27 Amps, with a displacement power factor of 0.95 across every speed range, and it offers a 97.5% rated operational efficiency at the nominal current and the rated line input.

The 20AD027A3NYNANC0 is designed to automatically detect ground faults, and it provides protection against ground faults as well as a transient voltage spike of up to 6000 Volts using Metal Oxide Varistors. This drive provides control via a sine-coded pulse width modulated (PWM) signal with a default carrier frequency of 4 kilohertz, and users can adjust the output voltage from 0 Volts to the rated motor voltage via the programmed output frequency (0 to 500 Hertz). It can be programmed for the Sensorless Vector control and the Vector control with the patented Force Technology designed for high-speed operation and torque control without the need for a feedback device. The 20AD027A3NYNANC0 features multiple programmed stop options, and it offers independently programmed acceleration and deceleration times, each programmed form 0 to 3600 seconds in 0.1-second increments. This drive allows for easy monitoring and control of drive parameters via a 7-line by 21-character LCD human-machine interface module (HMI) with simple text display and a multi-language option. The 20AD027A3NYNANC0 has an airtight and watertight IP20-rated industrial enclosure suitable for panel mounting, and it is designed for use around environments with an ambient temperature range of 0 to 50 degrees Celsius. The 20AD027A3NYNANC0 has an approximate weight of 9.3 kilograms, and an approximate shipping dimensions of 219.9 x 350.0 x 180.0 millimeters.
