The model 20DD2P1A3EYYA1NBA from Allen-Bradley, part of the PowerFlex 700S series, serves as an adjustable frequency AC drive. This unit works effectively with a three-phase voltage input of 480 volts AC. It is rated for an input current of 2.1 amps, making it suitable for smaller motor control applications.
The drive is housed in a NEMA Type 1 enclosure that meets the standards for IP20 protection, suitable for indoor use. Users benefit from a full numeric LCD that simplifies control and monitoring tasks. A quick start guide accompanies the unit to assist with setup.
For safety and efficiency, this model features an IGBT-based braking system and an adjustable bus undervoltage trip setting. Thermal protection is in place through a heat sink thermistor, which is actively monitored by a microprocessor. This ensures that overheating conditions can trigger an overtemperature trip, providing robust protection for the drive.
In the event of a brief power interruption, the logic control ride-thru functionality maintains operation for 0.25 seconds when the drive is not running. Additionally, it is capable of delivering power ride-thru for up to 15 milliseconds during full load scenarios. These features ensure that the 20DD2P1A3EYYA1NBA drives remain operational and reliable even under varying conditions.
