20DD261A3EYNNEBCL

The 20DD261A3EYNNEBCL from Allen-Bradley serves as an adjustable frequency AC drive, offering performance and flexibility in powerful industrial applications. This model is capable of handling an input voltage of 480V AC with three-phase connectivity. The input current rating reaches up to 261 amps, making it suitable for demanding motor control needs.

The drive is protected by an IP20-rated enclosure, adhering to NEMA Type 1 standards, ensuring it operates effectively in designated operational environments. User interaction is achieved via a full numeric LCD, allowing for easy status monitoring and setting adjustments. For initial setup assistance, a quick start guide is included.

Focused on operational reliability, this AC drive integrates IGBT braking technology for dynamic control. It is also equipped with an adjustable bus undervoltage trip feature, improving safety measures during operation. For thermal management, the heat sink thermistor is monitored by a dedicated microprocessor, which activates an overtemperature trip when conditions exceed safe limits.

The drive maintains efficiency with a logic control ride-thru capability of 0.25 seconds, allowing it to stay functional during brief power interruptions. In instances of full load, it can sustain power for 15 milliseconds, ensuring minimal disruption in processes. The 20DD261A3EYNNEBCL combines essential features to enhance performance in contemporary industrial settings.
