The PowerFlex 700S series presents the 20DD500A3ENNBNNNN adjustable frequency AC drive. Designed to operate on a three-phase system, this model runs on 480V AC, delivering extensive functionality for motor control applications. Capable of handling an input current of 500 amps, it stands ready for heavy-duty duties in various industrial scenarios.
The enclosure features an IP20 rating, compliant with NEMA Type 1 standards, ensuring it can withstand typical environmental conditions. For ease of use, a full numeric LCD is implemented for straightforward interaction, offering users quick access to operational parameters and settings.
This drive does not include a braking mechanism, yet enhances safety with an adjustable bus undervoltage trip. Additionally, thermal management is addressed through a heat sink thermistor, continuously monitored by an internal microprocessor, which triggers an overtemperature trip when necessary.
Operational reliability is further supported by a logic control ride-thru capability of 0.25 seconds when the drive is inactive, ensuring system stability. The drive also provides a brief power ride-thru period of 15 milliseconds at full load, maintaining function despite transient disturbances. Included documentation comprises a quick start guide for installation assistance.
