20DR156A0NYNANASE

The 20DR156A0NYNANASE model from Allen-Bradley represents an adjustable frequency AC drive designed for high-performance applications. With a capability to handle 650V DC, this unit effectively operates in three-phase setups. It is rated for a maximum input current of 156 amps, enabling it to manage significant power demands efficiently.

This drive comes with an IP20 enclosure conforming to NEMA Type 1 standards, which allows for deployment in controlled environments. The human-machine interface on this model is simplified with a blank cover, promoting streamlined installation and reduced complexity. Users should note that no documentation is provided for this product, which may necessitate prior experience for effective use.

The 20DR156A0NYNANASE incorporates an IGBT braking system that enhances its operational safety and performance. This drive includes an adjustable bus undervoltage trip feature, allowing customization based on specific application requirements. The system ensures protection against excessive temperatures through a heat sink thermistor monitored by a microprocessor. This mechanism activates an overtemperature trip if the unit experiences thermal stress.

For additional operational stability, the logic control ride-thru feature provides a buffer of 0.25 seconds when the drive is inactive, while it can support power ride-thru for up to 15 milliseconds during peak load conditions. Overall, the 20DR156A0NYNANASE is designed for versatility and reliability in demanding industrial applications.
