20DD500N0ENNBDANE

The 20DD500N0ENNBDANE is an adjustable frequency AC drive manufactured by Allen-Bradley, part of Rockwell Automation's offerings. It is designed to run effectively at a voltage level of 480 volts AC while handling input currents up to 500 amps. Constructed to operate in three-phase settings, this device is particularly useful for applications demanding robust and reliable motor control.

Unlike many drives, it features an open enclosure with an IP00 rating, allowing for straightforward installation without protective casing. The human-machine interface comes with a blank cover, requiring external provisions for direct operation or monitoring. The unit includes a quick start guide to simplify initial setup.

This model does not feature a braking mechanism, but it offers an adjustable bus undervoltage trip to safeguard the equipment from potentially damaging voltage drops. It is equipped with a heat sink thermistor that is monitored by an integrated microprocessor, which ensures safe operational temperatures by triggering an overtemp trip as necessary.

Further, during inactive periods, the unit provides logic control ride-thru capability lasting 0.25 seconds, helping to sustain essential functions without interruption. Additionally, it can perform power ride-thru for as long as 15 milliseconds at full load to maintain performance during brief power fluctuations. The 20DD500N0ENNBDANE drive is engineered to meet the challenges of demanding industrial environments while offering efficient performance.
