20DD3P4A3EYNANNNA

The Allen-Bradley 20DD3P4A3EYNANNNA is designed as an adjustable frequency AC drive, intended explicitly for three-phase applications at a voltage of 480V AC. It has a normal-duty current rating of 3.4 amps, which makes it suitable for a range of industrial applications that require precise motor control.

This drive is housed within an enclosure rated IP20, conforming to NEMA Type 1 standards. This ensures it is fit for indoor use with limited protection from dust and contact. Users will find a full numeric LCD that serves as the human-machine interface, allowing for straightforward navigation and operation of the device.

The 20DD3P4A3EYNANNNA features an IGBT braking system that enhances the control of motor dynamics and response. In terms of safety, the drive incorporates an adjustable bus undervoltage trip feature, enabling users to tailor operational thresholds to their needs.

A microprocessor monitors the heat sink thermistor and triggers an overtemperature trip if conditions exceed safe limits. For operational stability, this drive possesses a logic control ride-thru capability lasting 0.25 seconds, effectively retaining settings when the device is not in motion. Additionally, it supports a power ride-thru duration of 15 milliseconds at full load, ensuring consistent performance during brief power interruptions. This combination of features provides a reliable solution for industrial applications requiring efficient motor control and management.
