20DD385A3ENNBEASE

The 20DD385A3ENNBEASE model, part of the PowerFlex 700S series from Allen-Bradley, is an adjustable-frequency AC drive suitable for industrial applications. It operates with a three-phase input at a voltage of 480V AC, allowing it to handle a significant normal-duty current of 385 amps effectively. This drive is housed within an IP20 enclosure that meets NEMA Type 1 specifications, suitable for typical indoor use and protection against dust.

A full numeric LCD facilitates user interaction and provides clear visibility into operational variables and settings. Notably, this drive does not incorporate a braking system, simplifying its design for specific motor control tasks.

An adjustable bus undervoltage trip enhances the safety features of the drive, allowing users to customize parameters to their operational needs. Integrated into the design is a heat sink thermistor that is continuously monitored by a microprocessor, which allows for effective thermal management and prevents overheating by triggering a trip if temperatures exceed safe limits.

For added reliability, the drive includes logic control ride-thru functionality that allows it to maintain operation during brief downtime for up to 0.25 seconds. Additionally, it has the capacity for power ride-thru during full load for up to 15 milliseconds, ensuring continuity in demanding situations. Overall, the 20DD385A3ENNBEASE AC drive is engineered to provide stability and efficiency in control across various industrial environments.
