The Allen-Bradley 20DD3P4A3NYYA1NNA is an adjustable frequency AC drive characterized by its three-phase operation capability at 480V AC. This drive manages a maximum normal-duty current of 3.4 amps, enhancing its applicability across diverse industrial settings.
Its construction includes an enclosure with an IP20 rating, meeting NEMA Type 1 protection standards against dust and moisture. An integral feature is the full numeric LCD, which provides essential information and features for user interaction.
For increased safety and operational reliability, this drive is equipped with an IGBT braking system and an adjustable bus undervoltage trip function, allowing tailored configurations to ensure consistent performance. The heat sink thermistor is actively monitored by a microprocessor, which initiates overtemperature trips if necessary, thus protecting against potential heat-related damage.
In terms of operational resilience, the 20DD3P4A3NYYA1NNA supports a logic control ride-thru capability of 0.25 seconds when not actively running. Furthermore, it is designed for power ride-thru support of up to 15 milliseconds when under full load, maintaining functionality during brief power interruptions. This combination of features ensures the drive's reliability and efficiency across various demanding applications.
