20DD385A3ENNBECNL

Part of the PowerFlex 700S series, the 20DD385A3ENNBECNL model functions as an adjustable-frequency AC drive engineered for precise control in industrial environments. It operates at a nominal voltage of 480V AC and is tailored for three-phase electrical systems. With a significant normal-duty current capacity of 385 amps, this unit effectively supports high-demand applications.

The drive is housed within an IP20-rated enclosure compliant with NEMA Type 1 ratings, ensuring it meets requirements for protection against dust and accidental contact during normal operating conditions. Interaction with the system is facilitated through a full numeric LCD display, enabling clear monitoring and control.

This drive does not feature a braking mechanism but includes essential safety measures, such as an adjustable bus undervoltage trip to protect against low-voltage situations. To manage temperature effectively, the heat sink thermistor is continuously monitored by an internal microprocessor. This feature prevents overheating by initiating an overtemperature trip when necessary.

Furthermore, the logic control ride-thru duration when the drive is not operating is set to 0.25 seconds, maintaining operational stability during brief disruptions. For extended reliability under load conditions, it accommodates power ride-thru for 15 milliseconds, ensuring that the performance remains stable even during temporary power fluctuations. The 20DD385A3ENNBECNL is designed for robustness and precision in managing motor control tasks.
