20DD385H0ENNBNANE

The 20DD385H0ENNBNANE from Allen-Bradley represents an advanced solution for adjustable frequency AC drive applications. This device operates efficiently at a voltage of 480V AC and is designed to support three-phase electrical systems with a maximum normal-duty current of 385 amps. Suitable for demanding industrial environments, the drive integrates a protective enclosure rated IP54 under NEMA Type 12 standards, ensuring durability and resilience. A Rittal construction combined with a conformal coating provides further safeguarding against harsh conditions.

The drive includes a blank cover as its human-machine interface, which is ideal for configurations where user access is minimal. Unlike some models, this unit does not include a braking system. However, it does feature an adjustable bus undervoltage trip that allows customization according to operational needs.

Thermal management is crucial in maintaining performance; thus, the heat sink thermistor is continuously monitored by an integrated microprocessor for overtemperature protection, ensuring reliable operation. Additionally, the 20DD385H0ENNBNANE supports a logic control ride-thru capability of 0.25 seconds during periods when the drive is not active. It also features a power ride-thru capability lasting 15 milliseconds during full load conditions, ensuring stability even during brief power interruptions.
