The 20DD3P4A0QYNA1NNA is part of the PowerFlex 700S series from Allen-Bradley, featuring an adjustable frequency design. This AC drive operates efficiently at a voltage rating of 480 volts AC and is configured for three-phase input voltage with a current limit of 3.4 amps. The unit’s IP20 enclosure meets NEMA Type 1 standards, ensuring basic protection against ingress of solid objects.
Notably, this drive does not incorporate a human-machine interface; instead, it is equipped with a blank cover, implying direct management through control systems. There is no documentation supplied with this model.
For braking duties, it employs an IGBT braking technology, which offers efficient stopping capabilities. Additionally, the adjustable bus undervoltage trip feature allows for customization to meet specific operational requirements.
The heat sink thermistor is actively supervised by a microprocessor, which implements overtemperature trip mechanisms to safeguard the unit. The design includes logic control ride-thru functionality that lasts for 0.25 seconds when the drive is idle, providing stability during short power fluctuations. Further, a power ride-thru option permits continued functionality for 15 milliseconds at full load, ensuring reliability in demanding conditions.
