20DC261A3EYNBNANE

The Allen-Bradley model 20DC261A3EYNBNANE is an adjustable-frequency AC drive engineered to enhance motor control precision. It functions efficiently within a three-phase arrangement and is rated for operation at 400V AC. The unit can draw up to 261 amps at this voltage level, which suits various industrial applications requiring robust performance.

Designed for reliability, the unit has an enclosure classified as IP20 according to NEMA Type 1 standards, offering protection in moderate environments. The drive features an easily accessible full numeric LCD, which provides an interface for monitoring and configurations.

The 20DC261A3EYNBNANE includes an IGBT braking system, ensuring effective control during operations. Its adjustable bus undervoltage trip setting contributes to enhanced operational safety. A microprocessor continuously monitors the heat sink thermistor, allowing for prompt action against overheating.

For additional reliability, the drive supports a logic control ride-thru capability of 0.25 seconds when the drive is not actively running. This is complemented by a power ride-thru feature that can sustain power for 15 milliseconds at full load, helping to secure operations in the event of brief power fluctuations. Overall, the design of the 20DC261A3EYNBNANE ensures it meets the demands of modern industrial usage.
