20DD3P4A3EYYACNNN

The 20DD3P4A3EYYACNNN by Allen-Bradley is engineered as an adjustable-frequency AC drive tailored for robust industrial applications. This drive can operate at a voltage of 480 volts AC, making it effective in three-phase systems. It accommodates a current rating of up to 3.4 amps, suitable for various load requirements.

This model is enclosed in a structure rated IP20, complying with NEMA Type 1 standards, which provides essential protection in indoor environments. For ease of use, it features a full numeric LCD display that aids operators in monitoring performance and settings.

In terms of functionality, the drive utilizes an IGBT technology for braking, enhancing its efficiency under varying operating conditions. To maintain operational safety, it includes an adjustable bus undervoltage trip feature, allowing users to customize the parameters according to their needs. Additionally, a heat sink thermistor is in place to monitor temperature levels and activate an overtemperature trip as necessary, thanks to a microprocessor controlling this feature.

While not operational, the drive offers logic control ride-thru for a brief period of 0.25 seconds, thus ensuring that vital settings are preserved during temporary interruptions. Furthermore, the device is capable of sustaining power for up to 15 milliseconds at full load during power fluctuations, ensuring stability and reliability in critical applications.
