20DD500A0ENNB1CNL

The Allen-Bradley 20DD500A0ENNB1CNL is an adjustable frequency AC drive engineered for optimum performance in industrial environments. Rated for a three-phase input voltage of 480V AC, this unit is capable of managing a maximum input current of 500 amps, which allows it to operate efficiently within high-demand applications.

Housed in an IP20-rated enclosure meeting NEMA Type 1 criteria, this device provides adequate protection against dust and contact. The interface does not feature a dedicated human-machine interface component; instead, it incorporates a blank cover that preserves its compact design. To facilitate setup and integration, a quick start guide is included in the package.

The model does not come equipped with an internal brake system, but it does incorporate an adjustable bus undervoltage trip feature for safeguarding the system during fluctuating conditions. Thermal protection is ensured by a heat sink thermistor, overseen by a microprocessor, which facilitates an overtemperature trip when necessary.

In terms of operational stability, the drive maintains logic control ride-thru capability of up to 0.25 seconds when not actively running, allowing the drive to remain operational during brief power interruptions. Additionally, during full load, the power ride-thru functionality is effective for 15 milliseconds, ensuring continuous operation during voltage fluctuations. The 20DD500A0ENNB1CNL model is well-suited for a variety of applications where reliable motor control and performance monitoring are critical.
