20DC105A0QYNA2NNA

The 20DC105A0QYNA2NNA model from Allen-Bradley represents an adjustable frequency AC drive within the PowerFlex 700S series. It is designed to run at a voltage level of 400 volts AC and accommodates three-phase operations with a normal duty current rating of 105 amps. The construction of this drive includes an enclosure that meets IP20 and NEMA Type 1 classifications, ensuring a suitable level of protection in typical environments.

This unit features a blank cover instead of a human-machine interface, simplifying its appearance and avoiding unnecessary components. However, it does not come with supplemental documentation.

For braking, the drive is equipped with an IGBT system, providing effective control during operation. The bus undervoltage trip can be adjusted to fit specific requirements, which adds versatility to its application. Thermal protection is facilitated by a heat sink thermistor that is actively monitored by a microprocessor. This system ensures that overheating issues are quickly addressed, contributing to the longevity and reliability of the drive.

Additionally, there is a logic control ride-thru capability lasting up to 0.25 seconds when the drive is not in operation, allowing for short interruptions without compromising functionality. In case of temporary power disturbances, the power ride-thru function maintains performance for 15 milliseconds at full load, which enhances overall system stability.
