20DE325A0ENNBNANK

Designed by Allen-Bradley as part of the PowerFlex 700S series, part number 20DE325A0ENNBNANK represents an adjustable-frequency AC drive optimal for high-voltage applications. This unit is rated for operation at 600 volts AC and utilizes a three-phase power supply. The drive's normal-duty current capacity is 325 amps, suitable for robust motor control tasks.

The unit's structure includes an IP20 enclosure compliant with NEMA Type 1 specifications, providing essential protection for internal components. It features a blank cover, omitting a dedicated human interface machine but allowing for flexible integration within existing systems.

Though it lacks a braking system, the drive has several essential safety features. An adjustable bus undervoltage trip can be set to protect against low power conditions, ensuring stability during operation. An integrated microprocessor closely monitors the heat sink thermistor to prevent overheating, activating an overtemperature trip if necessary.

The device has a logic control ride-thru of 0.25 seconds while the drive is not actively running, maintaining system stability during brief power interruptions. In addition, it can sustain a power ride-thru of 15 milliseconds at full load, protecting critical operations during transient voltage dips. Overall, the 20DE325A0ENNBNANK model is designed for efficiency and reliability in demanding industrial environments.
