20DR125A0EYNANAEL

Operating under the catalog number 20DR125A0EYNANAEL, the adjustable frequency AC drive by Allen-Bradley is a component engineered for three-phase electrical systems. It efficiently manages a voltage of 650V DC and can handle up to 125 amps of input current. The construction features an IP20 enclosure that aligns with NEMA Type 1 ratings, making it suitable for use in environments where protection against dust and moisture is moderate.

The design incorporates a blank cover, lacking any human-machine interface. This means external controls may be required for operation adjustments. Key safety measures include an adjustable bus undervoltage trip feature that can be tailored for specific application requirements. Furthermore, the drive is equipped with an IGBT braking system, providing effective stopping power when needed.

For enhanced thermal management, the unit includes a heat sink thermistor, which is actively monitored by a microprocessor to prevent overheating during operations. In terms of operational stability, the drive supports logic control ride-thru capability lasting about 0.25 seconds while in idle status, enhancing reliability during brief power interruptions. Additionally, it is designed to maintain power for approximately 15 milliseconds under full load conditions, ensuring consistent performance when unexpected voltage drops occur.
