The 20DD156A3EYNACNNN is categorized as an adjustable frequency AC drive from the PowerFlex 700S series by Allen-Bradley. It operates on a 480V AC three-phase input and is capable of dealing with a maximum normal-duty current of 156 amps. The device features an enclosure that is rated IP20, which complies with NEMA Type 1 standards, ensuring basic protection for indoor environments. A full numeric LCD serves as the human-machine interface, allowing for straightforward control and monitoring of operational parameters.
The drive is equipped with IGBT technology for effective braking capabilities. Users can also utilize an adjustable bus undervoltage trip feature to configure settings according to specific operational needs. Additionally, this drive incorporates a heat sink thermistor that is actively monitored by a microprocessor, which provides safety by triggering an overtemperature trip when necessary.
For added resilience, the logic control ride-thru time is set at 0.25 seconds when the drive is not in operation. Meanwhile, the power ride-thru can maintain operation for a maximum of 15 milliseconds under full load conditions. The 20DD156A3EYNACNNN is engineered for demanding industrial applications, providing reliable performance and flexibility in control.
