20DC011A3NYNA2NBA

The 20DC011A3NYNA2NBA adjustable frequency AC drive belongs to the PowerFlex 700S series by Allen-Bradley. Designed to function under demanding industrial conditions, this drive operates efficiently at a voltage of 400 volts AC, specifically made for three-phase applications. It has a maximum input current rating of 11.5 amps at this voltage, providing robust performance for motor control.

This model features an IP20 rated enclosure, meeting NEMA Type 1 standards, to protect internal components from foreign objects. User interface options include a full numeric LCD, which allows for straightforward operation and monitoring. However, users should note that the unit does not come with accompanying documentation, necessitating external references for setup and configuration.

The drive uses an IGBT braking mechanism, ensuring reliable stopping power during operations. Safety and performance are enhanced further with its adjustable bus undervoltage trip feature, which helps manage unexpected voltage drops. Additionally, the heat sink thermistor is actively monitored by a microprocessor to trigger an overtemp trip if temperatures exceed preset thresholds.

For operational stability, the logic control ride-thru provides continued functionality for up to 0.25 seconds when the drive is not actively running, while the power ride-thru capability allows it to maintain essential performance for 15 milliseconds at full load during brief power interruptions. Overall, the 20DC011A3NYNA2NBA offers essential features and specifications suitable for various control applications.
