The 20DR125A0NNNACAAE, part of the Allen-Bradley PowerFlex 700S lineup, is engineered as an adjustable frequency AC drive. This drive is specified for use with a high voltage input of 650V DC and can operate effectively with three-phase systems. It has an input capacity of 125 amps, allowing it to power substantial loads with efficiency.
An IP20 enclosure, compliant with NEMA Type 1, protects the interior components while facilitating installation in non-harsh environments. This model features a blank cover in place of a human-machine interface, indicating a reliance on external control systems for operation. Notably, documentation for this drive is not provided.
The 20DR125A0NNNACAAE does not include an integrated braking system, prioritizing compact design for specific applications. The device features an adjustable bus undervoltage trip, enhancing safety during unexpected voltage conditions. Thermal management is ensured through a heat sink thermistor, continuously monitored by an internal microprocessor to detect overheating situations. For enhanced reliability, the drive supports logic control ride-thru for up to 0.25 seconds when inactive and can maintain operational stability for up to 15 milliseconds at full load during power fluctuations.
