The 20DD156A3EYNANBUE stands out in the PowerFlex 700S series from Allen-Bradley as an adjustable frequency AC drive built for demanding industrial applications. This drive operates at an input voltage of 480V AC and is designed for three-phase systems, efficiently managing a maximum normal-duty current of 156 amperes. The IP20-rated enclosure ensures the unit is protected while also adhering to NEMA Type 1 standards, making it suitable for stable indoor environments.
This model includes a full numeric LCD human interface for user-friendliness, allowing operators to manage and monitor performance easily. The drive features an IGBT braking system designed to provide reliable deceleration, while the adjustable bus undervoltage trip offers customization based on operational requirements.
A monitored heat sink thermistor effectively handles thermal management, which functions under the supervision of a microprocessor to prevent overheating. The device boasts a logic control ride-thru capability lasting 0.25 seconds, maintaining operational stability when not in use, and offers power ride-thru for up to 15 milliseconds during full load conditions. The 20DD156A3EYNANBUE is not only powerful but also flexible in integrating with various industrial and automation setups.
