20DD500B3ENNBNANE

The 20DD500B3ENNBNANE is a robust adjustable frequency AC drive developed by Allen-Bradley as part of the PowerFlex 700S series. This drive is engineered for three-phase electrical systems and operates effectively at 480 volts AC. Its input capabilities allow for a maximum current of 500 amps, making it well-suited for intensive industrial usage.

Housed in an IP20 enclosure that conforms to NEMA Type 1 standards, this drive is designed for indoor installation. The enclosure is treated with conformal coating to enhance its resilience against environmental factors. Operators interact with the drive through a full numeric LCD, simplifying configuration and monitoring processes.

While the 20DD500B3ENNBNANE does not feature an integrated braking system, it compensates by providing an adjustable bus undervoltage trip. This ensures that the drive can safeguard against potential faults related to bus voltage dips.

To monitor thermal conditions, the drive incorporates a heat sink thermistor monitored by a microprocessor. This system helps in preventing overheating by issuing an overtemp trip when required. The device also allows for a logic control ride-thru for up to 0.25 seconds when inactive, which is crucial during brief power interruptions. For times of full load, it offers power ride-thru support for up to 15 milliseconds, securing performance continuity in varied operational scenarios.
