The Allen-Bradley 20DC170A3ENNACNNN is part of the PowerFlex 700S series. This adjustable-frequency AC drive operates efficiently at 400 volts AC, making it suitable for various industrial applications requiring a three-phase connection. With a current capacity of 170 amps in normal-duty applications, it delivers powerful performance while maintaining operational stability.
Constructed within an IP20-rated enclosure classified as NEMA Type 1, this device is designed for indoor use where dust and moisture levels are moderate. A full numeric LCD serves as the human interface machine, providing essential information and allowing users to monitor drive performance easily.
However, the drive does not feature a brake system. It includes an adjustable bus undervoltage trip, allowing users to tailor protections based on application requirements. Temperature management is supported by a heat sink thermistor, which is monitored by an integrated microprocessor to avert overheating.
When the drive is not operational, it supports a logic control ride-thru capability lasting 0.25 seconds. Additionally, the system can sustain a power ride-thru period of 15 milliseconds at full load, helping to protect against brief power outages. The combination of these features ensures that the 20DC170A3ENNACNNN drive will deliver effective performance in varied operational environments.
