20DD3P4A3QYNA1NBA

The 20DD3P4A3QYNA1NBA adjustable frequency AC drive, produced by Allen-Bradley, falls under the PowerFlex 700S series. This device operates at a rated voltage of 480 volts AC and is structured for use in three-phase systems. It has the capability to handle a normal-duty current of 3.4 amps, accommodating applications requiring moderate to high power levels.

The drive's design includes an enclosure rated at IP20, in accordance with NEMA Type 1 standards, providing adequate protection for indoor usage. Control and configuration are facilitated through a full numeric LCD, which offers a clear interface for monitoring operation.

The device utilizes IGBT technology for its braking mechanism, contributing to its efficiency and performance stability. Equipped with an adjustable bus undervoltage trip, it enhances operational safety by allowing users to set their desired threshold.

For thermal management, the integrated heat sink thermistor is actively monitored by a microprocessor, which triggers an overtemperature trip if necessary to prevent damage. Additionally, it supports a logic control ride-thru time of 0.25 seconds while not running, ensuring continuity of operations during brief power interruptions. Under full load conditions, the drive can maintain power for 15 milliseconds, making it suitable for critical applications requiring reliability and precision.
