The 20DR125A0NNNACNNN model belongs to Allen-Bradley's PowerFlex 700S series as an adaptive frequency AC drive. This unit is engineered to operate at a voltage level of 650V DC, making it well-suited for demanding industrial environments. With a rated current capacity of 125 amps, it is equipped to handle significant loads across its three-phase structure.
This drive's enclosure has an IP20 rating, corresponding to NEMA Type 1 standards, offering essential protection against solid foreign objects in controlled settings. Notably, it comes with a blank cover in place of a user interface, streamlining design and installation. It does not include braking features, which may be beneficial in specific applications.
The 20DR125A0NNNACNNN integrates smart safety features, including an adjustable trip mechanism for bus undervoltage conditions. The unit is equipped with a heat sink thermistor monitored by a microprocessor, activating an over-temperature trip if measurements exceed safe thresholds. Furthermore, when the drive is not in operation, it can sustain logic control for up to 0.25 seconds. It also possesses the ability to maintain power for 15 milliseconds under full load, ensuring continuity in power supply amidst transient disturbances.
