20DC261A0ENNBNANE

This adjustable-frequency AC drive, part number 20DC261A0ENNBNANE, is part of the Allen-Bradley PowerFlex 700S series. It operates on a three-phase system at 400V AC and has a significant normal duty current capacity, rated at 261 amps, which allows it to perform effectively.

Designed with an IP20 enclosure compliant with NEMA Type 1 standards, this device is suitable for indoor use in controlled environments. The unit features a blank cover for its human-machine interface, removing any extraneous components or distractions and allowing for streamlined operation.

The absence of a braking system on this model suggests a specific application focus where braking functionality is not required. However, it compensates with several safety features, including an adjustable bus undervoltage trip. This capability safeguards the unit during voltage drops, enhancing reliability. Additionally, it features a heat sink thermistor that is constantly monitored by a microprocessor, providing overtemperature protection to prevent overheating.

For logical control, the drive can maintain functionality for 0.25 seconds while not in operation and offers a power ride-thru for up to 15 milliseconds when at full load, ensuring stability during minor power interruptions. Overall, the 20DC261A0ENNBNANE drive combines robust specifications, safety features, and a user-friendly interface, making it an ideal option for high-performance motor control.
