Designed by Allen-Bradley, the 20DC261A0ENNBNASE is part of the PowerFlex 700S series and functions as an adjustable-frequency AC drive. This device operates at 400 volts AC and can deliver 261 amps in a three-phase configuration. Its robust design is enveloped in an IP20-rated enclosure that adheres to NEMA Type 1 standards, making it suitable for various environments while allowing ample cooling.

The drive does not include a braking system, yet it features an adjustable bus undervoltage trip for enhanced operational safety. A significant feature is the heat sink thermistor, which is continuously monitored by the drive's internal microprocessor, ensuring efficient operation by preventing overheating through a responsive overtemperature trip mechanism.

The design comprises a blank cover for the human interface machine option, streamlining the physical profile of the unit.

For reliability during brief power interruptions, the device includes a logic control ride-thru that supports 0.25 seconds while the drive is inactive. Power ride-thru capability extends for 15 milliseconds at full operational load, ensuring critical functions remain unaffected during minor fluctuations. Overall, the 20DC261A0ENNBNASE drive demonstrates robust performance and intelligent design for various industrial applications.
