20DD156A3NYNANNNN

The Allen-Bradley 20DD156A3NYNANNNN is a robust adjustable frequency AC drive designed for use with three-phase systems. Operating at a nominal voltage of 480 volts AC, this unit is adept at handling a maximum normal-duty current of 156 amps. This drive is integrated into an IP20-rated enclosure, compliant with NEMA Type 1 protective standards, and suitable for typical indoor environments.

A full numeric LCD facilitates user interaction, providing clear visibility of operational parameters and settings. Although this model does not come with accompanying documentation, the user interface is straightforward enough for effective operation. The drive employs IGBT technology for braking, enabling efficient motor control.

It features an adjustable bus undervoltage trip, allowing users to modify protection settings based on their specific application requirements. Thermal safety is maintained through a monitored heat sink thermistor, overseen by a microprocessor, which activates an overtemperature trip when required.

During inactive periods, the drive ensures stability with a logic control ride-thru duration of 0.25 seconds. Furthermore, it provides power ride-thru capabilities for 15 milliseconds at full load to handle brief interruptions effectively. The 20DD156A3NYNANNNN drive is, therefore, a reliable choice for high-performance motor control in industrial applications.
