Adaptation to heavy load conditions in the metallurgical industry: INVT GD600A multi drive frequency converter

1、 150% torque ride through capability to handle heavy impact loads
The steel rolling, continuous casting and other equipment in the metallurgical industry often face heavy impact loads, which require extremely high overload capacity for frequency converters. INVT GD600A supports electric/generator stable ride through with 150% rated torque, which can maintain stable output torque during sudden load changes and avoid equipment shutdown. At the same time, the product has an overload capacity of 200% rated current for 1 second, which can easily cope with the start-up and impact conditions of metallurgical equipment.

2、 Input current equalization technology, supporting multiple rectifiers and parallel operation
For high-power metallurgical equipment, a single rectifier unit often cannot meet the power requirements and multiple rectifier units need to be used in parallel. The rectification unit of GD600A supports direct parallel operation without the need for additional reactors at the input end, and the input current imbalance is less than 10%, which can achieve uniform load distribution among multiple rectification units and ensure stable operation of high-power systems.

3、 Forced air cooling for stable operation in high-temperature environments
The high ambient temperature in the metallurgical workshop poses a severe challenge to the heat dissipation capability of the frequency converter. INVT GD600A adopts an efficient forced air cooling design, and the optimized cooling air duct can quickly remove the heat generated by equipment operation. The product supports a wide temperature range of 10~50 ° C, and can be used with a reduced rating above 40 ° C. It can operate stably for a long time in high-temperature environments in metallurgical workshops.

4、 Wide voltage input range, suitable for power grid fluctuation conditions
The power grid of metallurgical enterprises often has significant voltage fluctuations, which can easily cause damage to the frequency converter. The input voltage range of GD600A is AC 380V (-15%)~440V (+10%), which can adapt to large voltage fluctuations in the power grid. At the same time, the product has a comprehensive input voltage abnormal protection function, including input phase loss, overvoltage, undervoltage, three-phase imbalance protection, etc., effectively protecting the equipment from the impact of power grid fluctuations.
