20DR156A3ENNACNNN

The part number 20DR156A3ENNACNNN from Allen-Bradley represents an adjustable frequency AC drive configured for 650V DC operation. This device operates efficiently in three-phase settings and can handle a maximum input current of 156 amps, making it suitable for medium to high-demand applications.

Protected by an IP20 enclosure, this drive complies with NEMA Type 1 standards, providing adequate safety in typical indoor environments. A full numeric LCD serves as the human interface, allowing easy programming and monitoring. Users will find a quick start guide included for immediate access to essential setup information.

The unit is designed without a braking function, which is ideal for specific applications. It also features an adjustable bus undervoltage trip to cater to varying operational requirements and ensure safety during operation. Thermal concerns are managed by a heat sink thermistor that continuously monitors temperature levels via an integrated microprocessor, effectively preventing overheating conditions.

For operational resilience, the drive can maintain logic control ride-thru for 0.25 seconds while not running. In the event of power fluctuations, a power ride-thru capability enables it to continue functioning for a brief duration of 15 milliseconds under full load conditions. Overall, the 20DR156A3ENNACNNN drive offers the reliability and features necessary for its intended applications.
