The model 20DD034A3NYNANNNN from Allen-Bradley is categorized as an adjustable frequency AC drive within the PowerFlex 700S series. This device operates at a nominal voltage of 480V AC and is designed for three-phase applications. With a significant input current capacity of 34 amps, it ensures reliable performance for a variety of industrial settings.
The drive features an IP20 enclosure rated under NEMA Type 1, providing basic environmental protection. User interactions are performed through a full numeric LCD, which allows for easy monitoring and adjustments.
This model employs IGBT braking technology for efficient motor control. Safety features include an adjustable bus undervoltage trip, allowing operators to set the parameters according to operational needs. The heat sink includes a thermistor that is actively monitored by a microprocessor, which triggers an overtemperature trip if necessary.
For resilience in operation, the 20DD034A3NYNANNNN supports logic control ride-thru for 0.25 seconds when not in use, helping maintain system stability during brief power interruptions. It also includes a 15-millisecond power ride-thru capability at full load, ensuring continuity in power supply during transient events.
