Part of the PowerFlex 700S series, the 20DD011A3NYYA1NNA AC drive is engineered for precision motor control. Operating at 480 volts AC, this model is optimized for three-phase systems. Its normal-duty current rating of 11 amps ensures effective performance in various applications.
The device is contained in an IP20 rated enclosure, conforming to NEMA Type 1 standards. This makes it suitable for standard indoor use. Users will find the full numeric LCD human-machine interface intuitive, facilitating straightforward control and monitoring.
The drive does not come with any additional documentation, simplifying its design. It incorporates an IGBT braking system for efficient motor management. To prevent damage from low voltage conditions, it features an adjustable bus undervoltage trip.
Additionally, the heat sink thermistor is managed by a microprocessor that monitors for overheating and activates an overtemperature trip when necessary. In cases of temporary power loss, the logic control can sustain operational stability for up to 0.25 seconds. The power ride-thru capability allows the system to maintain functionality for 15 milliseconds at full load, ensuring minimal disruption to operations.
