The Allen-Bradley 20DD385A3ENNBNNNN is classified as an adjustable frequency AC drive. This particular model is engineered to work effectively in three-phase systems at a voltage of 480V AC. It is capable of managing normal-duty currents of 385 amps, making this drive proficient for various industrial tasks.
Conforming to the NEMA Type 1 standards, the device is enclosed in an IP20-rated housing, signaling adequate protection for indoor conditions. The unit facilitates user interaction through a full numeric LCD, allowing for clear access to operational parameters and settings.
Notably, the 20DD385A3ENNBNNNN does not feature a braking system. Instead, the integrated adjustable bus undervoltage trip provides essential safety against voltage drops. Moreover, the heat sink is equipped with a thermistor monitored by a microprocessor that activates an overtemperature trip if required.
This drive supports a logic control ride-thru capability of 0.25 seconds when the drive is inactive. Additionally, it can continue to function for up to 15 milliseconds at full load during unforeseen power disturbances. These features collectively contribute to the reliability and operational efficiency of the 20DD385A3ENNBNNNN in demanding industrial applications.
