20DR125A0NYNANNNN

The 20DR125A0NYNANNNN model from Allen-Bradley, part of the PowerFlex 700S series, serves as an adjustable frequency AC drive. Designed for high-performance applications, it operates at a rated voltage of 650 volts DC. The drive effectively manages three-phase power configurations and is capable of handling an input current of 125 amps.

Encased in an IP20-rated enclosure that conforms to NEMA Type 1 standards, this unit is not suited for environments with high exposure to dust or moisture. There is no built-in human-machine interface, as it comes equipped with a blank cover. Users will not find detailed documentation with the unit, so system integration will require proper planning.

In terms of safety features, the drive includes an IGBT brake for reliable operation and an adjustable bus undervoltage trip, which can be customized to prevent operational disruptions during voltage fluctuations. The heat sink is monitored via a thermistor by a microprocessor, enabling effective thermal management and ensuring that the system doesn’t overheat. The logic control provides a ride-thru duration of 0.25 seconds when the drive is not in operation, allowing for brief interruptions without loss of functionality. Additionally, under full load conditions, it supports power ride-thru for up to 15 milliseconds, which helps maintain operational efficiency during brief power dips.
