20DC260A0EYNANDNL

The 20DC260A0EYNANDNL from Allen-Bradley is categorized as an adjustable frequency AC drive, ideal for robust performance in demanding applications. Operating under three-phase power, this model is tailored for 400V AC environments, efficiently managing a normal-duty current rating of up to 260 amps.

Protected by an IP20-rated enclosure that meets NEMA Type 1 requirements, the unit is built for durability in standard industrial settings. It does not feature a human-machine interface but has a blank cover, which simplifies its design.

For braking, this AC drive uses IGBT technology, providing effective motor control. Noteworthy safety aspects include an adjustable bus undervoltage trip, which can be modified based on specific operational needs. Furthermore, the heat sink thermistor is actively monitored by a microprocessor, ensuring that overheating is detected and addressed through an automatic overtemp trip function.

In terms of operational continuity, the system offers a logic control ride-thru capability lasting 0.25 seconds when the drive is not in operation. This helps maintain functionality during brief supply interruptions. Additionally, the device supports power ride-thru for 15 milliseconds at full load, allowing for stable operation even in the event of momentary voltage sags. The 20DC260A0EYNANDNL drive demonstrates reliability and versatility, making it suitable for various industrial motor control requirements.
