20DJ156A3QNNANACE

The 20DJ156A3QNNANACE model is an adjustable frequency AC drive from Allen-Bradley, part of the PowerFlex 700S series. This device operates efficiently at an input voltage of 600V AC, designed specifically for three-phase applications. It has an input current rating of 156 amps. The unit itself is housed in an IP20 enclosure that meets the NEMA Type 1 specifications, making it suitable for a standard indoor environment.

A full numeric LCD serves as the human-machine interface, ensuring operators can easily monitor and control settings. However, the absence of included documentation suggests familiarity with the product is beneficial for setup and operation.

While the drive does not include a braking system, it is equipped with an adjustable bus undervoltage trip feature for operational safety. Thermal performance is effectively managed by a heat sink thermistor that gets constant monitoring from an integrated microprocessor. This prevents overheating and ensures dependable operation.

Regarding stability during power fluctuations, the drive can maintain logic control ride-thru for up to 0.25 seconds when not actively in use. In scenarios requiring it to withstand brief power losses while under full load, it supports power ride-thru for a maximum of 15 milliseconds. Overall, the 20DJ156A3QNNANACE is designed to offer reliable performance in demanding applications.
