The 20DD034A3NYNA1NBA, manufactured by Allen-Bradley and part of the PowerFlex 700S series, is an adjustable frequency AC drive optimized for three-phase applications. It supports an input voltage of 480 volts AC and can handle an impressive input current of 34 amps. This allows for reliable performance in industrial environments requiring robust motor control.
The drive is housed in an IP20-rated enclosure, compliant with NEMA Type 1 standards, making it suitable for indoor installation. Its full numeric LCD provides an effective interface for ease of operation and monitoring. However, it does not come with documentation.
For enhanced operation, the 20DD034A3NYNA1NBA features an IGBT braking system to manage speed control effectively. The system includes an adjustable bus undervoltage trip that can be set according to specific operational requirements. A heat sink thermistor is monitored by a microprocessor, which activates an overtemperature trip to prevent overheating during extended use.
The logic control ride-thru function allows the drive to maintain operation for 0.25 seconds when inactive. Additionally, power ride-thru capability is ensured for 15 milliseconds under full load conditions, making it a reliable choice for various industrial motor control applications.
