20DR125A3EYNA2CSL

The Allen-Bradley 20DR125A3EYNA2CSL is part of the PowerFlex 700S series, designed primarily for adjustable frequency applications in harsh industrial settings. This model operates effectively at a high voltage of 650V DC, utilizing a three-phase system to deliver reliable performance. It can handle up to 125 amps of input current, making it suitable for robust motor control requirements.

The drive features an IP20-rated enclosure consistent with NEMA Type 1 standards, thereby providing adequate protection in typical indoor environments. Interaction with the device is facilitated through a full numeric LCD, which allows clear visibility for monitoring operational parameters.

Included documentation comprises a quick start guide to aid users during setup. The 20DR125A3EYNA2CSL is equipped with an IGBT braking mechanism designed to enhance functionality during operation. Safety is further prioritized through an adjustable bus undervoltage trip, letting users set thresholds appropriate for their specific applications.

To prevent over-temperature incidents, the heat sink thermistor is consistently monitored by an internal microprocessor, ensuring the drive functions within safe limits. The drive also contains logic control ride-thru capabilities, functioning for 0.25 seconds when it is inactive. Additionally, it maintains power ride-thru for 15 milliseconds during peak load conditions, which contributes to its reliability in maintaining performance through power fluctuations.
