The 20DC011A3NYNA1NNA from Allen-Bradley represents a reliable adjustable frequency drive within the PowerFlex 700S series. Functioning with a 400V AC input, it operates effectively across three phases. This drive's input current capacity is rated at 11.5 amps at 400 volts, positioning it as a versatile solution for motor control.
Encased in an IP20-rated structure that meets NEMA Type 1 standards, this unit is built for environments where basic dust and moisture protection is required. User interaction is simplified through the full numeric LCD human-machine interface. However, there are no additional documentation materials provided.
An IGBT braking system enhances performance, ensuring smooth operation during stop conditions. Protection features include an adjustable bus undervoltage trip, safeguarding the unit from low voltage conditions. Additionally, the heat sink thermistor is closely monitored by a microprocessor, which activates an overtemperature trip to maintain safe operating temperatures.
In event of power disruptions, the unit supports a logic control ride-thru duration of 0.25 seconds when not operating, while it is designed for power ride-thru support for a stable 15 milliseconds at full load. This combination of features contributes to the drive's effectiveness in demanding applications.
