Allen Bradley 20BD034A3AYNACN0 Used Surplus

The 20BD034A3AYNACN0 is an adjustable frequency AC drive by Allen-Bradley. It is part of the PowerFlex 700 series of drives by Allen-Bradley/Rockwell Automation. It uses a ControlNet (Coax) adapter for communication. This adapter introduces the drive to the manufacturing process. The running status of the communication activity can be viewed from the LED indicator on the front face. The drive has a braking system which uses switching regenerative energy without any external chopper circuits. The 20BD034A3AYNACN0 drive also uses its own patented Force technology which provides excellent low-speed performance without using an encoder feedback device.

The 20BD034A3AYNACN0 runs on 480 Volts of AC power and the amperage rating of this AC drive is 34 Amps. The power output of the drive is 25 Horsepower. For controlling AC motors, the drive uses a Sine-coded PWM with a programmable carrier frequency. The drive can be supplied with 6-pulse or 18-pulse power in a configured package. The drive features a carrier frequency of 2, 4, 8, and 10 kHz. The output frequency range for standard control is in the range of 0 to 400 Hertz and for vector control, it has a range from 0 to 420 Hertz. The drive has a different frequency accuracy for digital and analog input. For digital input, it lies within +/- 0.01% of the set output frequency whereas, for analog input, it lies within +/- 0.4% of the maximum output frequency. The 20BD034A3AYNACN0 supports a panel mount for mounting purposes. The panel mount has an IP20 rated enclosure. It is not waterproof and hence special care should be taken during the installation and the operation of the drive. The drive is attached with a numeric keypad and an LCD which acts as an interface module between the operator and the drive. Both the CE filter and CM choke are present in this drive.
