Part number 20DD040A0NYNA1NNA is an adjustable frequency AC drive from the Allen-Bradley PowerFlex 700S series. It operates at a nominal voltage of 480 volts AC with a three-phase configuration. The drive can support a normal-duty current of 40 amps, catering to demanding industrial applications.
This device is designed with a NEMA Type 1 compliant, IP20-rated enclosure, making it suitable for use in environments with typical indoor conditions. It has a blank cover interface option, which means it does not feature a pre-installed human-machine interaction panel, providing a streamlined installation approach.
Among its features, the drive employs an IGBT braking system for efficient control. The bus undervoltage trip is adjustable, allowing for configuration based on specific needs. Additionally, the heat sink is monitored by a microprocessor to detect overheating. Should temperatures exceed safe limits, an overtemp trip is initiated.
For short interruptions, the drive maintains logic control ride-thru for 0.25 seconds when it is not actively running. Meanwhile, it also supports a power ride-thru capability lasting 15 milliseconds when operating at full load, an essential feature for maintaining operational stability in fluctuating power conditions.
