ALLEN-BRADLEY INVERTER PowerFlex 755 22kW – 20G11NC043JA0NNNNNN

The PowerFlex 755 is an advanced inverter that is part of the PowerFlex series of drives. This innovative drive is designed to provide precise speed control of electric motors in a variety of industrial applications.

The Allen-Bradley PowerFlex 755 – 20G11NC043JA0NNNNN is rated at 43 amps at 22 kW. This drive is designed with a blanking plate instead of a keypad/LCD module, however it is possible to install a HIM.

This device is a 400 VAC input unit. Its rated power is 22 kW. This drive also has 5 option slots for additional VFD modules and a dynamic brake transistor built into the drive itself. It is also worth noting that this AC drive has a jumper installed in its design, which may be relevant for specific configurations and applications.

The Allen-Bradley 20G11NC043JA0NNNNN frequency converter is part of the PowerFlex 755 family of drives designed to provide instant motor control in a variety of industrial applications. This drive has a 400 VAC 3-phase input voltage with a tolerance of +/-10% of the nominal input voltage. The displacement power factor is 0.98 and the operating efficiency reaches 97.5% at rated values.

It is characterized by an internal mains voltage fuse in the converter module, which protects the device against mains voltage transients and surge protection. In addition, the predictive diagnostics engine helps identify faults, contributing to quick repairs and minimizing downtime and maintenance costs.

The 20G11NC043JA0NNNNN drive is equipped with an integrated EMC line filter and dynamic braking transistor. Built-in I/O and five optional slots (for power, communication, safety, I/O and feedback) provide versatile configuration possibilities. As standard, it is equipped with an Ethernet port, which facilitates control and configuration.

The drive offers a variety of motor control options including Volts per Hertz, Sensorless Vector Control, Flux Vector Control and Permanent Magnet Control. It is suitable for both closed-loop speed, open-loop speed and fine speed and torque control.

The dimensions of this converter are 454 x 190 x 212 mm, and the operating temperature range is from 0 to 50 degrees Celsius. The device has an open housing and is ideal for use in a wide industrial spectrum.

The PowerFlex 755 Series models are available in a variety of variants, giving you the ability to choose the right solution based on your specific application needs. Cooperation with communication interfaces enables advanced control and monitoring of the drive both locally and remotely. The PowerFlex 755 complies with modern industry standards, enabling integration with control and supervision systems, which in turn translates into increased productivity and process accuracy.
