20DD077A3NYNA2NNB

The 20DD077A3NYNA2NNB model crafted by Allen-Bradley operates as an adjustable frequency AC drive, specifically engineered for situations requiring three-phase 480V AC input. This unit supports a significant normal-duty current capacity of 77 amps, allowing it to meet demanding industrial requirements.

This drive, housed within an IP20-compliant enclosure, aligns with NEMA Type 1 standards, providing a basic level of protection against dust and other contaminants. Operators benefit from a full numeric LCD interface, facilitating straightforward usage and monitoring capabilities. However, this model does not come with accompanying documentation.

An IGBT braking system is integrated to ensure reliable motor control. One of its notable features is the adjustable bus undervoltage trip, which helps safeguard the equipment against irregular voltage levels. Heat management is also a key feature of this drive, with a heat sink thermistor that is monitored by a microprocessor. This system offers protection by triggering an overtemperature trip when thresholds are exceeded.

For enhanced reliability during temporary power disruptions, this drive supports a logic control ride-thru duration of 0.25 seconds while inactive. During full load conditions, it can withstand power fluctuations for up to 15 milliseconds. The 20DD077A3NYNA2NNB AC drive offers robust functionalities that cater to various industrial automation applications.
