The 20DC261N0EYNBNNNN adjustable frequency AC drive by Allen-Bradley is engineered for high-performance applications requiring substantial power management. It operates at a voltage rating of 400V AC and supports a three-phase configuration. This unit can handle an impressive current of 261 amps (normal duty).
Designed with an IP20-rated enclosure that adheres to NEMA Type 1 standards, the drive ensures adequate protection from dust and accidental contact. It features a blank cover for its human interface machine, providing a clean appearance and simplified operation.
The model is equipped with an IGBT braking system, which enhances operational control and efficiency. Additionally, the adjustable bus undervoltage trip feature allows users to set specific parameters based on their application needs. A heat sink thermistor is integrated into the design and is continuously monitored by a microprocessor to protect against overheating conditions.
For resilience against power interruptions, the drive offers a logic control ride-thru duration of 0.25 seconds when it is not running. It can maintain operation during power fluctuations for up to 15 milliseconds when at full load. The 20DC261N0EYNBNNNN is a robust choice for those requiring precision and reliability in their motor control systems.
