The 20DD460A3NNNB1CEL is a sophisticated adjustable frequency AC drive from Allen-Bradley's PowerFlex 700S series. With a voltage rating of 480V AC, this drive is designed for robust three-phase electrical systems, accommodating input currents reaching up to 460 amps.
Its compact design is encapsulated in an IP20 enclosure, consistent with NEMA Type 1 specifications, suitable for various industrial environments. The control interface includes a full numeric LCD, simplifying monitoring and operations. However, this drive does not include a braking feature.
For safety and protection, it offers an adjustable bus undervoltage trip feature to safeguard against low voltage scenarios. The system also integrates a heat sink thermistor that operates under microprocessor supervision to thwart overheating through an overtemp trip function. This unit allows for a logic control ride-thru duration of 0.25 seconds when the drive is not operational, thus ensuring continued stability.
Moreover, the 20DD460A3NNNB1CEL sustains power ride-thru for up to 15 milliseconds at full load, thus providing operational resilience during brief power supply fluctuations. Its combination of features aims to deliver effective motor control in demanding applications.
