The PowerFlex 700S series features the 20DJ385N0NNNBCNNN adjustable frequency AC drive, which is engineered to handle demanding industrial tasks. This drive is designed to operate with a voltage input of 650V DC, providing the necessary power for high-performance applications. It has an impressive normal-duty current rating of 385 amps, easily accommodating substantial electrical loads.
The drive is housed in an open enclosure rated at IP00, ensuring basic protection suitable for controlled environments. A notable design aspect of this unit is its blank cover for the human interface machine option, and it does not include a built-in documentation package.
Safety and reliability are key characteristics of this drive. It features an adjustable bus undervoltage trip, allowing customization per operational requirements. A heat sink thermistor is integrated and continuously monitored by a microprocessor, which activates an overtemperature trip if the heat exceeds safe levels.
When the drive is not actively running, it maintains logic control for up to 0.25 seconds, ensuring stability in the face of temporary power interruptions. Additionally, it can sustain performance under full load for up to 15 milliseconds during power outages, highlighting its resilience during critical operations.
