20DD8P0A5NYYACNNN

The Allen-Bradley 20DD8P0A5NYYACNNN is an adjustable frequency AC drive within the PowerFlex 700S series. This unit is engineered for three-phase operation with an input voltage of 480V AC. It can handle a maximum input of 8 amps efficiently, aligning with the needs of a variety of motor applications. The drive is protected within an IP20 rated enclosure, compliant with NEMA Type 1 specifications, making it suitable for indoor environments with limited exposure to contaminants.

User interaction with the drive is achieved through a programmable LCD, emphasizing concise control access. However, it should be noted that there is no supplemental documentation accompanying this model. The device employs IGBT braking technology, providing a reliable stopping mechanism when necessary. Additionally, an adjustable bus undervoltage trip is incorporated to enhance operational safety.

For thermal management, a heat sink thermistor is actively monitored by a microprocessor, which ensures functionally safe operation by triggering an overtemperature trip if action is required. The drive supports logic control ride-thru for a period of 0.25 seconds while not running, allowing for system stability during short interruptions. Additionally, it offers 15 milliseconds of power ride-thru capability under full load, thereby ensuring continued functionality during momentary power loss.
