20DE650N0NNNBNCEL

The 20DE650N0NNNBNCEL model from the PowerFlex 700S series by Allen-Bradley serves as a high-capacity adjustable frequency AC drive. This unit is engineered to provide reliable performance in demanding industrial environments. Operating at a voltage level of 600V AC, it is specifically tailored for three-phase applications. The drive's maximum normal-duty current rating is 650 amps, allowing it to handle substantial loads effectively.

The enclosure is classified as open, with an IP00 rating. This means it does not protect the drive against dust or moisture intrusion, emphasizing the need for installation in controlled environments. Notably, the drive lacks a standard human-machine interface, featuring only a blank cover.

This unit does not include a braking feature, which may limit its use in certain applications where deceleration control is necessary. However, it is robust and has safety features such as an adjustable bus undervoltage trip, enabling it to be tailored to specific operational conditions.

For thermal management, the integrated heat sink thermistor continuously monitors temperature, with overtemperature conditions tracked by a microprocessor. Regarding reliability during operation, the drive supports a logic control ride-thru function that extends up to 0.25 seconds during idle periods. It can sustain power ride-thru for 15 milliseconds under full load, ensuring consistent performance even during temporary power disturbances.
