20DD3P4A3NYNA1NNA

The 20DD3P4A3NYNA1NNA model from Allen-Bradley is an adjustable-frequency AC drive tailored for three-phase applications. It operates effectively at a nominal voltage of 480 volts AC and has a current rating of 3.4 amps, which positions it for various industrial tasks requiring reliable motor control.

This drive features an enclosure rated at IP20, complying with NEMA Type 1 specifications, and is suitable for clean indoor environments. A full numeric LCD display facilitates user interaction, providing clear insight into operational metrics. The model does not include documentation.

The drive employs an IGBT braking strategy, optimizing performance during operations. Safety mechanisms include an adjustable bus undervoltage trip to prevent operational failures. Additionally, the heat sink thermistor is actively monitored by a microprocessor, triggering an overtemperature trip in the event of overheating to maintain system integrity.

In terms of operational continuity, the 20DD3P4A3NYNA1NNA also incorporates a logic control ride-thru duration of 0.25 seconds during non-operation, ensuring stability amid brief power interruptions. Furthermore, the device supports power ride-thru capabilities for 15 milliseconds when operating under full load conditions, enhancing its reliability in dynamic electrical environments. This model is efficiently designed for safe and robust interactions across various industrial applications.
