20DD261A0EYNNNANE

The 20DD261A0EYNNNANE adjustable frequency AC drive, produced by Allen-Bradley, operates at a robust 480 volts AC. This model is specifically designed for use in three-phase systems, supporting a significant input current capacity of 261 amps.

The drive is secured in an enclosure rated at IP20, complying with NEMA Type 1 standards, providing adequate protection for its internal components. Users will find a blank cover for the human-machine interface, which simplifies integration into existing control systems. A quick start guide is included for efficient setup and operational commencement.

For effective braking, the unit utilizes an IGBT system, ensuring reliable motor control performance. An adjustable bus undervoltage trip feature allows customization of operational settings, enhancing safety protocols.

The thermal performance of the drive is managed by a heat sink thermistor, which is actively monitored by a microprocessor, ready to trip if overtemperature conditions are detected. This AC drive is also equipped with a logic control ride-thru capability, which lasts for 0.25 seconds when the drive is not active, minimizing disruptions. During full load operations, it maintains power for up to 15 milliseconds, ensuring system stability when faced with transient conditions. Overall, the 20DD261A0EYNNNANE is well-engineered for effective industrial applications.
