The part number 20DD300N3ENNNNASE, part of the Allen-Bradley PowerFlex 700S series, is an adjustable-frequency AC drive. It is configured to function with a three-phase voltage of 480V AC. The unit can handle a maximum normal-duty current of 300 amps, making it suitable for demanding industrial setups.
With an IP20 enclosure that complies with NEMA Type 1 standards, the drive offers adequate protection for indoor environments. Operators can utilize the full numeric LCD interface for straightforward monitoring and setup adjustments.
Notably, the model does not feature a braking system. However, safety measures include an adjustable bus undervoltage trip to safeguard against low voltage conditions. The integrated heat sink thermistor offers protection against overheating and is monitored continuously by a microprocessor.
The drive extends logic control ride-thru capabilities for 0.25 seconds when not actively operational, ensuring consistent behavior during brief interruptions. In scenarios where power is lost, it possesses a power ride-thru capacity for up to 15 milliseconds at full load, which supports ongoing operation and enhances reliability in industrial applications.
