20G14GB312JA0NNNNN

The 20G14GB312JA0NNNNN model is a powerful AC drive developed by Allen Bradley as part of the PowerFlex 755 series. This unit operates with an input configuration allowing for DC input accompanied by a precharge feature. It stands out with a voltage rating of 240 volts AC, but can be programmed for 208 volts AC and can also support DC inputs up to 325 volts.

With an output current of 312 amps under normal duty, the drive provides an impressive power output of 125 horsepower, making it suitable for various demanding industrial applications. In terms of communication capabilities, this drive integrates a built-in Ethernet port, ensuring straightforward network connectivity.

The enclosure is rated IP54, complying with NEMA/UL Type 12 protection, making this unit quite robust against dust and moisture ingress. Additional features include a filtering capability with a common mode jumper already installed. Dynamic braking within this drive is managed by an internal transistor, contributing to effective stopping and speed control.

An aspect to note about this model is the absence of a door-mounted Human Interface Module (HIM), which might be relevant for specific installation environments. Designed for efficiency, the 20G14GB312JA0NNNNN achieves a remarkable efficiency rating of 97.5% at rated amps and nominal line voltages. It functions effectively in ambient temperatures ranging from 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) and sustains relative humidity levels between 5 to 95% without condensation. For storage, it can withstand temperatures perched between -40 to 70 degrees Celsius, or -40 to 158 degrees Fahrenheit, making this drive adaptable to various operational needs.
