The part number 20DD125A3NYNA2NBB is an adjustable frequency AC drive produced by Allen-Bradley, falling under the PowerFlex 700S series. Designed for three-phase systems, this drive operates at a voltage of 480V AC and can manage an input current of up to 125 amps.
Housed within an enclosure rated IP20, this unit complies with NEMA Type 1 standards, making it suitable for indoor use where standard dust and moisture protection is required. The device employs a full numeric LCD for its human interface, facilitating easy adjustments and monitoring. However, no additional documentation is provided with the unit.
The 20DD125A3NYNA2NBB features an IGBT braking system, which ensures effective motor control and performance. Its adjustable bus undervoltage trip option allows customization based on operational needs. The drive also incorporates a heat sink thermistor that is continuously surveyed by a microprocessor, enabling a rapid response to any overheating incidents.
Operational resilience is enhanced by a 0.25-second logic control ride-thru time when the unit is idle, as well as a 15-millisecond power ride-thru capability during full load conditions. Thus, the 20DD125A3NYNA2NBB is engineered to deliver reliable performance across a range of industrial applications.
