20DD077A3EYNACCNL

The 20DD077A3EYNACCNL part from Allen-Bradley is categorized as an adjustable frequency AC drive designed for high performance in industrial settings. This device operates under a voltage rating of 480V AC and is adept at handling three-phase electrical systems. It is rated for up to 77 amps of normal-duty current, making it suitable for intensive applications.

Housed within an enclosure that complies with IP20 and NEMA Type 1 specifications, this drive is designed for indoor use. A fully numeric LCD interface provides users with critical operational feedback and easy access to settings.

The drive utilizes an IGBT braking system to promote efficiency and performance. Built-in safety features include an adjustable bus undervoltage trip, allowing settings to be tailored based on operational needs. For temperature management, a heat sink thermistor is actively monitored by a microprocessor, which triggers an over-temp trip in conditions of excessive heat.

The 20DD077A3EYNACCNL allows for 0.25 seconds of logic control ride-thru while the drive is inactive, facilitating system stability during brief power disruptions. Moreover, it features a power ride-thru capability that lasts 15 milliseconds at full load to enhance performance during transient voltage conditions. This combination of features enables this drive to meet the rigorous requirements of various industrial applications.
