20DD460A3ENNBNNNN

The Allen-Bradley 20DD460A3ENNBNNNN adjustable frequency AC drive operates efficiently within a three-phase system setup. It handles an input voltage of 480V AC and supports a maximum normal-duty current of 460 amps, making it ideal for demanding industrial environments. This AC drive is engineered for durability, as evidenced by its IP20-rated enclosure complying with NEMA Type 1 standards, which protects the unit from environmental factors commonly found in industrial settings.

A full numeric LCD facilitates user interaction, providing clear visibility into operational statuses and settings. Notably, the 20DD460A3ENNBNNNN model does not include a built-in braking system, which may be a consideration for certain applications.

A significant feature of this drive is the adjustable bus undervoltage trip, which allows customization to safeguard against low voltage conditions. Additionally, thermal safety is ensured through a heat sink thermistor, which is continuously monitored by an internal microprocessor to activate an overtemperature trip if needed.

Operational stability is enhanced with logic control ride-thru capabilities, allowing the drive to maintain settings for 0.25 seconds during idle periods. Furthermore, it provides a power ride-thru for up to 15 milliseconds at full load, which helps maintain functionality during brief power disruptions. This drive represents a solid choice for diverse applications requiring reliable motor control in an industrial context.
