INVT GD28-2R2G-4 AC 3PH 380V–480V frequency converter

The Hardcore Drive Strength of INVT GD28 Series Inverter

The complex working conditions of industrial production place extremely high demands on the driving performance, response speed, and environmental adaptability of frequency converters. The INVT GD28 series agile universal frequency converter, with its hardcore performance configuration, has achieved a leap in the ability of universal frequency conversion products and can easily cope with various harsh industrial driving scenarios.

The GD28 series frequency converter is equipped with industry-leading sensorless vector control technology, achieving comprehensive breakthroughs in core performance. In asynchronous motor mode, a high starting torque of 200% can be output at a speed of 0.5Hz. In synchronous motor mode, a starting torque of 150% can be output at 2.5Hz, perfectly adapting to the low-frequency load starting requirements of the equipment. Whether it is heavy-duty extrusion of the extruder or light load operation of the fan and water pump, stable and accurate driving control can be achieved. The torque control accuracy of the product is less than 5%, the torque response time is less than 10ms, and it can quickly respond to sudden load changes, ensuring the stability and processing accuracy of equipment operation.

In response to the pain points of power grid fluctuations in industrial production, the INVT GD28 series universal frequency converter is equipped with an instantaneous power failure without stopping function. When the power grid drops instantly, the frequency converter can continue to operate within the effective time with the help of feedback energy, avoiding unexpected equipment shutdown, especially suitable for production scenarios that require high continuity of equipment operation. At the same time, the product supports speed tracking function, which can quickly capture the motor speed, achieve smooth start without impact, reduce downtime losses, and ensure continuous operation of the production line.

In terms of load adaptability, the GD28 series agile frequency converter adopts a dual rated design, with an overload capacity of 150%/60s of the rated output current in heavy load mode and 110%/60s in light load mode. It also supports two types of motors, induction motor and permanent magnet synchronous motor, and is compatible with V/F and SVC control modes, truly achieving "one machine for multiple uses". From high torque start-up to fast response, from continuous operation guarantee to full scenario load adaptation, the INVT GD28 series provides a stable and reliable power core for various industrial equipment with excellent driving performance.
