20DE590A0ENNBNCNK

The 20DE590A0ENNBNCNK from Allen-Bradley, part of the PowerFlex 700S series, is an adjustable frequency AC drive. It is designed to operate under three-phase power conditions and caters to applications requiring a 600V AC voltage supply. With a maximum normal-duty current of 590 amps, this unit is geared toward handling substantial load demands.

Compliant with the NEMA Type 1 standard, the drive is housed in an IP20-rated enclosure, ensuring it is suited for indoor environments and protected from solid contaminants. The design features a blank cover, indicating that there is no built-in human-machine interface for direct user control.

The 20DE590A0ENNBNCNK does not incorporate a braking mechanism yet features an adjustable bus undervoltage trip to prevent operational disruptions during voltage drops. Thermal management is facilitated by a heat sink thermistor that is continuously monitored by a microprocessor. This ensures the drive's temperature remains within safe limits while also triggering an overtemperature trip if required.

When the drive is not in operation, a logic control ride-thru capability is maintained for 0.25 seconds, allowing for brief electrical disturbances without affecting performance. Furthermore, the device can sustain power ride-thru for up to 15 milliseconds while operating at full load, promoting reliability and performance in various industrial applications.
