20DC170A3NYNACNBN

The 20DC170A3NYNACNBN is an adjustable frequency AC drive designed by Allen-Bradley, under Rockwell Automation's PowerFlex 700S series. This drive is capable of operating at 400V AC, specifically designed for three-phase systems. With a normal-duty current rating of 170 amps, it effectively manages substantial loads.

The unit is engineered with an IP20 and NEMA Type 1 enclosure. For user interfacing and control, it features a full numeric LCD, providing visibility and control over various operational parameters. However, it does not come with any accompanying documentation for setup or operation.

Key functionalities of the 20DC170A3NYNACNBN include an IGBT brake system which enhances operational performance during stops and makes performance adjustments seamless. An adjustable bus undervoltage trip feature is available, allowing operators to set thresholds according to the demands of their specific applications.

Thermal management is also prioritized; an onboard microprocessor constantly monitors a heat sink thermistor to ensure safe operating temperatures. The logic control ride-thru capability lasts for 0.25 seconds during periods when the drive is not engaged. Additionally, it offers power ride-thru support for up to 15 milliseconds at full load, ensuring stability during transient conditions. This makes the 20DC170A3NYNACNBN effective for a variety of industrial applications requiring dependable motor control.
