The Allen-Bradley 20DC261N0EYNBDNNN is a sophisticated adjustable frequency AC drive that performs efficiently across multiple applications. This model operates at a voltage of 400V AC and is structured for three-phase configurations. It can accommodate up to 261 amps of normal duty current, which makes it suitable for high-demand environments.
The unit is designed for standard indoor conditions and is encased in an IP20-rated housing compliant with NEMA Type 1 specifications. Its human-machine interface option is only a blank cover, allowing for a minimalistic setup without any overt controls. The drive is equipped with an IGBT braking system that enhances operational efficacy during control actions.
Safety features remain a priority; the adjustable bus undervoltage trip lets users customize parameters according to specific system requirements. A heat sink thermistor continuously checks temperature conditions, monitored by a microprocessor for automatic over-temp tripping.
This model also offers logical control ride-thru capability for up to 0.25 seconds when not running. In cases of power fluctuations, it holds the power ride-thru capability for 15 milliseconds at full load, ensuring stability during brief interruptions.
