20DD500N3ENNBRNNN

The 20DD500N3ENNBRNNN adjustable frequency AC drive is manufactured by Allen-Bradley, part of the PowerFlex 700S series. This drive efficiently operates at 480V AC and is configured for three-phase applications, making it a suitable choice for various industrial automation needs. It is capable of accommodating an input current rating of 500 amps, thus supporting significant load requirements.

The design of this drive features an open enclosure rated as IP00, which emphasizes the unit's suitability for internal locations where debris or moisture is not a concern. A full numeric LCD enables easy interaction, providing clear operational details at a glance. Users benefit from the included quick start guide for straightforward setup procedures.

The 20DD500N3ENNBRNNN does not have a built-in braking system, but it compensates with adjustable bus undervoltage trip settings to prevent operational issues due to low voltage scenarios. An integrated heat sink thermistor is continuously monitored by a microprocessor, effectively detecting and responding to temperature shifts to prevent overheating.

For added reliability in maintaining stable power conditions, the unit features a logic control ride-thru capability of 0.25 seconds when the drive is not actively running. Additionally, it can support brief power interruptions, maintaining functionality for up to 15 milliseconds while under full load, allowing for continual operation in dynamic industrial environments.
