20DD034A3NYNA1NNA

The 20DD034A3NYNA1NNA is an adjustable frequency AC drive developed by Allen-Bradley, a brand of Rockwell Automation. This unit functions effectively at 480 volts AC within three-phase configurations and is capable of managing an input current of 34 amps, suitable for various industrial applications.

The drive is housed within an enclosure that meets IP20 ratings, conforming to NEMA Type 1 standards. This provides adequate protection against non-hazardous environmental factors, allowing the drive to perform reliably indoors. A full numeric LCD serves as the interface, allowing easy monitoring and adjustments by the operator. However, there is no accompanying documentation for installation or operational guidelines.

Utilizing an IGBT braking system, the drive ensures effective control over the motors it operates. Enhanced safety is provided by an adjustable bus undervoltage trip feature, allowing customization based on specific operational needs or preferences. Thermal management is facilitated by a heat sink thermistor that is continually overseen by the microprocessor, which will trigger an overtemperature trip if necessary.

For operational stability, this AC drive supports a logic control ride-thru period of 0.25 seconds, ensuring continuity during brief power interruptions. Additionally, it can sustain power ride-thru for up to 15 milliseconds while under full load, enhancing reliability and performance in dynamic industrial applications.
