20DD500ACENNBEBNE

The 20DD500ACENNBEBNE, a product from Allen-Bradley within the PowerFlex 700S series, serves as a highly versatile adjustable frequency AC drive. This unit requires a three-phase power supply at a nominal voltage of 480V AC. It is capable of handling input currents up to 500 amps, making it suitable for various high-power industrial applications.

Constructed with an enclosure rated at IP20 and complying with NEMA Type 1 standards, the drive facilitates use in environments with low exposure to dirt and moisture. The human interface is highlighted by a full numeric LCD, designed for door mounting, which allows for straightforward monitoring and operation.

Users may refer to the included quick start guide for assistance in setup and initial configuration. The drive does not feature an integrated braking mechanism, but it includes an adjustable bus undervoltage trip to enhance operational safety. Thermal management is ensured through a heat sink thermistor, continuously monitored by a microprocessor, which activates an overtemperature trip if necessary.

For operational stability, the logic control ride-thru capability allows the drive to continue functioning for 0.25 seconds even when the drive is not running. Additionally, it can hold power for up to 15 milliseconds under full load, thereby providing resilience against brief power sags that may occur in the electrical supply.
