20DD261A3EYNBCASE

The 20DD261A3EYNBCASE model, part of Allen-Bradley’s PowerFlex 700S series, serves as a high-capacity adjustable frequency AC drive. Functioning within three-phase configurations at 480V AC, it supports an impressive input current of 261 amps. This drive is engineered for robust industrial applications, ensuring reliable performance under substantial loads.

Housed in an IP20 enclosure, which adheres to NEMA Type 1 standards, it provides basic protection for indoor use. The user interface consists of a full numeric LCD, which facilitates easy operation and monitoring of the drive's status. Users will find a quick start guide included, simplifying installation procedures.

This drive utilizes IGBT technology for effective braking, contributing to efficient motor control. In addition, it features an adjustable bus undervoltage trip for enhanced operational flexibility, allowing configuration based on application needs.

Thermal management is a critical element in the design; thus, a heat sink thermistor is incorporated and monitored by a microprocessor, which activates an overtemperature trip to ensure reliability. The drive also includes a logic control ride-thru time of 0.25 seconds when the unit is not in operation, alongside a power ride-thru capability of 15 milliseconds under full load conditions, allowing it to maintain functionality during brief power for interruptions.
