20DD385ACENNBNANE

The 20DD385ACENNBNANE represents an advanced adjustable-frequency AC drive designed for intensive applications. Operating at 480 volts AC in a three-phase setup, it provides substantial power handling with a maximum normal-duty current rating of 385 amps. The drive's construction follows NEMA Type 1 standards and is encapsulated within an IP20 enclosure that offers protection in typical indoor settings.

A notable feature of this drive is its human-machine interface mechanism, which consists of a full numeric LCD display. This interface is conveniently mounted on the door, allowing for straightforward access and monitoring of operational parameters. In terms of safety, the drive includes an adjustable bus undervoltage trip function, which is essential for protecting against low-voltage conditions. There is no braking system integrated into the model. Additionally, the heat sink thermistor is monitored by a microprocessor that triggers an overtemperature shutdown if needed.

This model also supports logic control ride-thru for a duration of 0.25 seconds when not in operation, ensuring settings are retained during brief power interruptions. Furthermore, it is capable of sustaining power ride-thru for 15 milliseconds at full load, aiding the drive in maintaining stability during transient conditions. The design and specifications of the 20DD385ACENNBNANE highlight its suitability for demanding motor control tasks.
