20G14ND477JA0NNNNN

The 20G14ND477JA0NNNNN AC drive from Allen Bradley’s PowerFlex 755 series is engineered to deliver robust performance. It accommodates a DC input type combined with a precharge feature, expanding its application range in diverse industrial settings. Rated for a maximum output of 400 horsepower (or 300 kW), this motor drive is well-suited for high-demand tasks.

Its ability to operate on voltages of up to 480 VAC and 650 VDC enhances its versatility across various systems. The non-dynamic current rating peaks at 477 A, ensuring that it can handle significant load variations effectively. This drive supports a line frequency of either 50 or 60 Hz, making it compatible with many electrical systems.

The drive's overall thermal management is supported by its specified operating temperature range of 0 to 50 °C (32 to 122 °F), with a storage temperature capability of -40 to 70 °C (-40 to 158 °F), thus ensuring reliable performance in extreme conditions. The filtering capability is built-in, which is beneficial for reducing electrical noise within the system environment.

The enclosure is rated IP00 / IP20 / NEMA Open / NEMA 1, providing various sealing options for differing environmental requirements. It's important to note that this model does not incorporate a door-mounted Human Interface Module (HIM). Additionally, the default common mode capacitor connection comes pre-installed as a jumper, optimizing setup efficiency. For effective load management, the internal transistor provides dynamic braking functionality, supporting quick deceleration when required.
