The Allen-Bradley 20DR125A0NNNANNNN, part of the PowerFlex 700S series, is an adjustable frequency AC drive engineered for high-performance applications. This model supports 650V DC operational voltage and operates with a three-phase power design. The drive is rated for an input current of up to 125 amps, accommodating significant electrical loads.
It features a compact and durable IP20 enclosure, aligned with NEMA Type 1 standards, suitable for a variety of industrial environments. The device does not include a braking system, facilitating straightforward functionality in typical motor control scenarios.
Safety mechanisms include an adjustable bus undervoltage trip, allowing settings to prevent operation under unsafe voltage conditions. Additionally, the drive is equipped with a heat sink thermistor that is actively monitored by a built-in microprocessor, ensuring immediate response if overheating occurs.
Operational stability is ensured with configurable logic control ride-thru support for 0.25 seconds during inactive states. Additionally, the drive can maintain power ride-thru for 15 milliseconds while under full load conditions, safeguarding against momentary power fluctuations.
