The part number 20DR125A3NNNACGNE is part of the Allen Bradley PowerFlex 700S series, defining itself as an adjustable frequency AC drive. Designed to function with a 650V DC power supply, this drive manages three-phase operations and can accommodate a significant current input rating of 125 amps.
Constructed with an IP20 enclosure that complies with NEMA Type 1 standards, the device is tailored for indoor environments, protecting it from direct exposure to dust or moisture. It is equipped with a full numeric LCD, enabling user-friendly access for monitoring and adjustments. However, it does not come with any documentation or a braking system included.
Safety features are key for operational reliability. The device includes an adjustable bus undervoltage trip mechanism to mitigate risks associated with low-voltage conditions. A heat sink thermistor is in place, actively monitored by an internal microprocessor, which can trigger an overtemperature trip if necessary.
When the unit is not in operation, it provides a logic control ride-thru capability of 0.25 seconds, which aids in maintaining stability during brief interruptions. Meanwhile, the power ride-thru function supports operation for up to 15 milliseconds under full load, ensuring resilient performance during sudden power disturbances.
