20DD3P4A3NYNACNBN

The Allen-Bradley 20DD3P4A3NYNACNBN is an adjustable frequency AC drive crafted for precise control in three-phase electrical systems, specifically operating at 480V AC. With a normal-duty current rating of 3.4 amps, this drive delivers reliable performance for varied applications.

Enclosed in an IP20-rated housing according to NEMA Type 1 standards, the model is built to provide protection in moderate environments. Furthermore, its human-machine interface is a full numeric LCD, allowing for clear visibility of settings and operations.

The device incorporates IGBT braking, enhancing efficiency and control in motor operations. It also features an adjustable bus undervoltage trip function, which is crucial for maintaining system safety during fluctuations in input voltage. For temperature regulation, the heat sink thermistor is actively monitored by a microprocessor, which serves to prevent overheating conditions, activating an over-temp trip when necessary.

When the drive is not operational, it supports a logic control ride-thru period of 0.25 seconds, preserving system settings during brief interruptions. Additionally, it includes a power ride-thru capability, maintaining functionality for up to 15 milliseconds under full load conditions. Overall, this module is designed to operate effectively in demanding settings, maintaining optimal performance under various industrial needs.
