20DD261A3EYNNNNNN

The 20DD261A3EYNNNNNN from Allen-Bradley is part of the PowerFlex 700S series, designed for efficient control of three-phase electrical systems. Rated at 480V AC, it can sustain a maximum input current of 261 amps. This capability makes it suitable for demanding applications requiring reliable power delivery.

It comes in an IP20 enclosure that complies with NEMA Type 1 standards, ensuring protection in typical indoor installations. For user convenience, a full numeric LCD is included, allowing operators to easily monitor and configure the drive settings. A quick start guide is provided to facilitate initial setup.

The braking system utilizes IGBT technology, ensuring efficient control during operation. An adjustable bus undervoltage trip feature enhances safety by allowing custom settings, catering to specific operational requirements. The heat sink is monitored by a thermistor integrated with a microprocessor, which activates an overtemperature trip to ensure the drive does not overheat.

The drive also provides logic control ride-thru functionality of 0.25 seconds when idle, improving stability in the event of brief interruptions. Additionally, it can maintain power for 15 milliseconds while at full load, ensuring performance continuity during temporary power fluctuations. The 20DD261A3EYNNNNNN is engineered to deliver reliable performance in demanding industrial settings.
