20DB028A0EYYANAAL

The Allen-Bradley 20DB028A0EYYANAAL is a robust adjustable frequency AC drive, optimized for industrial use. This model operates efficiently with a three-phase input at a nominal voltage of 240V AC, making it suitable for a range of applications. The device can handle 32.2 amps at a 208V input, adapting well to various control systems and machinery requirements.

Designed with an IP20 rating, this drive meets NEMA Type 1 specifications. This level of protection is suitable for indoor use where dust and accidental contact are considerations. The interface for the human-machine relationship is addressed through a blank cover, providing simplicity in design. Included with the drive is a Quick Start Guide to facilitate initial setup and operation.

This unit employs an IGBT brake which enhances braking performance and reliability. An adjustable bus undervoltage trip function is incorporated to safeguard the drive against potential low voltage conditions.

Monitoring of the heat sink thermistor is critical for the drive’s operation, as it is overseen by a microprocessor to prevent overheating through an overtemperature trip function. For logic control functionality, the device supports a ride-thru time of 0.25 seconds when the drive is not running, which helps maintain control stability during brief power interruptions. In contrast, the power ride-thru provides support for 15 milliseconds at full load, ensuring minimal disruption to connected loads during fluctuations.
