20DD385N0ENNBNNNN

The Allen-Bradley 20DD385N0ENNBNNNN adjustable frequency AC drive is built to perform efficiently in challenging environments. Designed primarily for three-phase systems, it operates at 480 volts AC. This unit can handle an impressive normal-duty current of up to 385 amps, making it a reliable choice for substantial industrial motor control applications.

The drive's enclosure is classified as open with an IP00 rating and is enhanced with a conformal coating. This protective layer safeguards internal components in less-than-ideal environments. The unit comes equipped with a blank cover, indicating it does not feature an interactive human-machine interface.

The inclusion of an adjustable bus undervoltage trip allows for flexible operation tailored to specific needs. Thermal safety is ensured through a heat sink thermistor that is actively monitored by a microprocessor. This system can initiate an over-temp trip when necessary to protect the drive from heat-related issues.

When the drive is inactive, it boasts a logic control ride-thru feature that can sustain operation for up to 0.25 seconds. Additionally, under full load conditions, it can maintain power for 15 milliseconds, allowing for brief interruptions without impacting performance. This model does not include any brake functionality, further emphasizing its design focus for continuous operation in various applications.
