The 20DD385ACENNBCBEE, part of Allen-Bradley's PowerFlex 700S series, is an adjustable frequency AC drive that operates on a three-phase power supply rated at 480V AC. This device offers a substantial normal-duty current limit of 385 amps, making it adept at managing high-demand applications efficiently. It has been constructed with an IP20-rated NEMA Type 1 enclosure, providing basic protection for indoor usage.
A notable characteristic of this model is the inclusion of a full numeric LCD human-machine interface mounted on the door, facilitating easy visibility and control for operators. The drive does not incorporate a braking system, but it does feature an adjustable bus undervoltage trip to enhance system safety.
The heat sink thermistor is monitored by a sophisticated microprocessor, which activates an overtemperature trip if necessary, thus mitigating risks associated with overheating. In routine operations, the drive supports a logic control ride-thru for 0.25 seconds when it is not actively running, providing stability during brief power interruptions. Furthermore, it has a power ride-thru capability lasting up to 15 milliseconds at full load, ensuring that operations can be maintained during temporary drops in supply.
