20DD300A0ENNBNANL

The 20DD300A0ENNBNANL model from the Allen-Bradley PowerFlex 700S series is an adjustable frequency AC drive engineered for demanding industrial applications. This unit operates on a three-phase system with a specified voltage of 480V AC, providing significant current handling capability with an input rating of up to 300 amps.

Enclosed in an IP20-rated enclosure that complies with NEMA Type 1 standards, the drive is suitable for typical indoor usage. Notably, this model does not feature a human interface, indicated by its blank cover. A quick start guide is included for straightforward setup and operational guidance.

The drive incorporates an adjustable bus undervoltage trip, which allows for configurable safety settings based on application requirements. Unlike some other drive models, it does not integrate a braking mechanism. For temperature management, a heat sink thermistor actively monitored by a microprocessor ensures safe operation by providing overtemperature protection.

In terms of operational reliability, the drive supports logic control ride-thru of 0.25 seconds when idle, helping to maintain operational stability during momentary power interruptions. It also provides power ride-thru capabilities for up to 15 milliseconds at full load, offering additional assurance in fluctuating power conditions. This combination of features makes the 20DD300A0ENNBNANL suitable for various applications requiring dependable motor control.
