20DD300A3NYNBCASE

The 20DD300A3NYNBCASE is an adjustable-frequency AC drive manufactured by Allen-Bradley, part of Rockwell Automation. This drive performs effectively within a three-phase setup and operates at 480V AC. Rated for 300 amps of normal-duty current and featuring a compact design, this unit is suitable for various industrial applications. Its current capacity is particularly useful in settings that demand reliable performance.

Constructed with an IP20 enclosure adhering to NEMA Type 1 criteria, this drive offers basic protection against dust and water ingress. Control and operation are facilitated through a full numeric LCD screen, which allows users to interact with the drive easily. It is essential to note that no documentation accompanies this drive. The braking mechanism is based on IGBT technology, providing efficient braking performance.

For enhanced safety and operational flexibility, the drive is equipped with an adjustable bus undervoltage trip, allowing users to set thresholds that fit their application needs. A microprocessor closely monitors the heat sink thermistor to prevent overheating, safeguarding the equipment during operation. Users will benefit from the logic control ride-thru feature, maintaining functionality for 0.25 seconds when not running. In addition, the drive is capable of sustaining power for up to 15 milliseconds at full load, ensuring stability during brief power fluctuations.
