20DJ38520NNNBCHNE

The 20DJ38520NNNBCHNE model, part of the Allen-Bradley PowerFlex 700S series, is an adjustable frequency AC drive intended for industrial applications. Designed to operate at 650V DC, it has a current rating of 385 amps, allowing for substantial power management capability in demanding environments. The device's enclosure meets the IP20 rating and complies with NEMA Type 1, indicating protection against dust and light contact.

It features a blank cover but does not come with accompanying documentation, necessitating familiarity with setup procedures. Unlike some models, this drive does not incorporate a braking system. However, safety is enhanced with an adjustable bus undervoltage trip feature that permits users to set the voltage thresholds as needed.

Thermal management is ensured by integrating a heat sink thermistor, which is monitored by a microprocessor to mitigate overtemperature situations effectively. The drive offers a logic control ride-thru functionality for up to 0.25 seconds when not in operation, ensuring stability during brief power interruptions. Additionally, it supports power ride-thru for 15 milliseconds at full load, aiding in reliable performance under fluctuating conditions. The 20DJ38520NNNBCHNE is engineered for efficiency and stability in various operational scenarios.
