20DD3P4A3EYYA1CNK

The 20DD3P4A3EYYA1CNK represents an adjustable frequency AC drive produced by Allen-Bradley, part of Rockwell Automation’s product line. Operating at 480 volts AC, this drive is configured for three-phase arrangements, making it suitable for various industrial machinery. It can handle a normal-duty current of 3.4 amps, which allows for efficient performance across different motor applications.

The drive is protected within an enclosure rated IP20, conforming to NEMA Type 1 standards and providing adequate safeguarding for indoor use. The human-machine interface features a full numeric LCD, which facilitates clear and straightforward monitoring of settings and operational parameters.

For braking, the 20DD3P4A3EYYA1CNK employs IGBT technology, allowing for effective control over motor dynamics. The device also incorporates an adjustable bus undervoltage trip feature to cater to varying operational conditions. Thermal performance is managed by a heat sink thermistor that is monitored continuously by an integrated microprocessor, which assists in preventing overheating.

In terms of reliability during power interruptions, the drive is equipped with a logic control ride-thru capability lasting 0.25 seconds when not actively running. This provides continuity in operations. It also includes power ride-thru functionality lasting up to 15 milliseconds at full load, ensuring the drive maintains its operations during brief disturbances.
