The 20DD027A0EYNA1CNL, part of the Allen-Bradley PowerFlex 700S series, is engineered as an adjustable-frequency AC drive. This unit can function at 480V AC and is optimal for three-phase power applications. It supports a normal-duty current rating of 27 Amps, facilitating various operational demands in industrial settings.
The drive is encased in an IP20-rated enclosure, compliant with NEMA Type 1 specifications, and ensures basic protection against dust and contact. Notably, the model features a blank cover instead of an interface module.
The IGBT braking mechanism offers reliable performance in controlling motor functions. Additionally, the adjustable bus undervoltage trip feature allows for customization according to specific system requirements. A microprocessor monitors the integrated thermistor on the heat sink, effectively preventing overheating by triggering an overtemperature trip when necessary.
This drive also incorporates logic control ride-thru capabilities that maintain operation for 0.25 seconds during inactive periods, ensuring stability. For brief moments of disruption, the power ride-thru is maintained for 15 milliseconds under full load conditions, adding an enhancement to operational reliability.
