The 20DD022A3NYNA3NNA adjustable frequency AC drive is engineered by Allen-Bradley and fits within the PowerFlex 700S series. Designed for robust performance, this unit operates effectively at 480V AC in three-phase configurations. It is rated for a normal-duty current of 22 amps, providing reliable control capabilities for various motor applications.
This drive is protected by an IP20-rated enclosure that conforms to NEMA Type 1 standards, allowing it to function in typical indoor settings with minimal dust and moisture exposure. The inclusion of a full numeric LCD offers an intuitive interface for monitoring and adjustment of parameters, enhancing user interaction with the drive.
An IGBT braking system is integrated for effective motor control, while the adjustable bus undervoltage trip provides enhanced operational safety. Thermal management is ensured by a heat sink thermistor that is actively monitored by a microprocessor for overtemperature protection. When not operational, the unit allows for a logic control ride-thru period of 0.25 seconds, safeguarding the functionality during brief disruptions. Furthermore, it can sustain power ride-thru of up to 15 milliseconds while under full load, promoting stability in fluctuating environments.
