20DE920A0ENNBNCNK

The 20DE920A0ENNBNCNK is an adjustable frequency AC drive manufactured by Allen-Bradley, a brand of Rockwell Automation. This unit is built to operate on a three-phase power supply with a maximum voltage of 600V AC. It is rated to handle input currents of up to 920 amps, making it suitable for high-current industrial applications requiring efficient motor control.

Housed within an IP20 enclosure that meets NEMA Type 1 standards, this drive is intended for use in environments where exposure to dust and moisture is minimal. It does not feature a visible human-machine interface, as it comes with a blank cover, which streamlines its design and installation.

Included with this drive is a quick start guide to assist with setup and configuration. The drive is equipped with an adjustable bus undervoltage trip system, providing flexibility for varying operational requirements.

Thermal management is addressed through a heat sink thermistor that the integrated microprocessor monitors. This functionality ensures the drive can manage temperature effectively, triggering an overtemperature trip when necessary. The logic control ride-thru capability allows for 0.25 seconds of operation when the drive is not running, while power ride-thru capability enables the system to maintain power for 15 milliseconds under full load conditions, bolstering reliability in transient situations.
