The 20DD385N0NNNBNANE model from Allen-Bradley is part of the PowerFlex 700S series. It consists of an adjustable-frequency AC drive ideal for industrial motor control. It is engineered for 480 volts AC and is suitable for various three-phase applications.
This drive can manage a substantial normal-duty current of 385 amps. Designed with an open enclosure with an IP00 rating, it features a conformal coat to protect against environmental factors. However, it does not include a human-machine interface module and lacks documentation.
Notably, this model does not integrate a braking function. It includes an adjustable bus undervoltage trip feature to safeguard against low-voltage conditions. Additionally, a heat sink thermistor is utilized to ensure thermal management, monitored by a microprocessor that helps prevent overheating situations.
In terms of resilience, the drive is capable of maintaining logic control ride-thru for a duration of 0.25 seconds when not in operation. Furthermore, it can sustain power for up to 15 milliseconds at full load in case of brief outages. Overall, the 20DD385N0NNNBNANE serves as a reliable choice for demanding industrial applications.
