The 20DD248A3NNNACGNE is an adjustable-frequency AC drive produced by Allen-Bradley, part of the PowerFlex 700S series. It is specialized for three-phase power configurations and operates at a voltage rating of 480V AC. This unit supports an impressive normal-duty current of 248 amps, easily catering to demanding industrial applications.
Encased in an IP20-rated NEMA Type 1 housing, the drive is engineered for indoor use and has protection against dust and physical contact. A full numeric LCD serves as the human-machine interface.
The drive does not come equipped with a braking system. However, it features an adjustable bus undervoltage trip designed to protect against voltage drops, thereby safeguarding connected equipment. Additionally, it employs a heat sink thermistor that is monitored by the microprocessor to prevent overheating and ensure operational reliability.
For operational stability, the 20DD248A3NNNACGNE has a logic control ride-thru capability lasting 0.25 seconds when it is not in operation. Under full load, it guarantees power ride-thru for 15 milliseconds, allowing the unit to remain functional during brief power interruptions. This combination of features makes the drive a versatile choice for various heavy-duty applications.
