20DD261A3EYNBNASE

The model 20DD261A3EYNBNASE from Allen-Bradley is an adjustable frequency AC drive tailored for three-phase operation at 480V AC. It is capable of handling a maximum input current of 261 amps, making it suitable for heavy-duty industrial applications. The drive's design includes an IGBT braking system, which enhances its stopping capabilities and overall responsiveness during operation.

This unit is housed in an enclosure rated as IP20, adhering to NEMA Type 1 standards, which provides adequate protection against dust and contact with electrical components. The human-machine interface is facilitated through a full numeric LCD, offering clear visibility for operating parameters and settings. A quick start guide is included to streamline installation.

Safety features of the 20DD261A3EYNBNASE include an adjustable bus undervoltage trip function, allowing users to customize settings according to their operational requirements. Thermal management is achieved with a heat sink thermistor monitored by a microprocessor, which ensures that the unit does not exceed safe temperature levels. Logic control ride-thru capabilities maintain functionality for 0.25 seconds when the drive is inactive, while power ride-thru can last for up to 15 milliseconds under full load conditions. These features and specifications make this drive well-suited for various industrial motor control needs.
