INVT GD200A frequency converter: the benchmark choice for industrial universal drives

1、 GD200A inverter core vector control technology unlocks ultimate driving performance
The INVT GD200A frequency converter, as the core universal frequency converter product of INVT, uses a high-performance DSP control system as the core platform and is equipped with industry-leading sensorless vector control technology, providing industry-leading driving performance for asynchronous motors. In terms of core parameters, the INVT GD200A frequency converter achieves asynchronous motor starting torque of 0.5Hz/150%, wide speed ratio of 1:100, fast dynamic response of<20ms, and high stable speed accuracy of ± 0.2%. Whether it is heavy-duty starting or precision speed regulation scenarios, it can output stable and reliable driving capabilities.
At the same time, the INVT GD200A frequency converter supports self-learning of motor parameters in both rotating and stationary modes. Rotating self-learning can meet the debugging needs of high-precision control scenarios, while stationary self-learning perfectly solves the on-site debugging problem of the motor being unable to disconnect from the load, greatly reducing the threshold for on-site debugging and making equipment debugging simpler and control accuracy more guaranteed.

2、 GD200A full dimensional hardware optimization, creating high adaptability for industrial sites
The INVT GD200A frequency converter has been fully optimized from the hardware design source for complex working conditions in industrial sites. The product adopts an independent air duct design, which effectively enhances the protection capability of the frequency converter and can adapt to various complex and harsh on-site environments. At the same time, with the flange installation method, it perfectly solves the heat dissipation problem inside the control cabinet, providing great convenience for customers' electrical cabinet heat dissipation design.
In terms of electromagnetic compatibility design, the GD200A frequency converter series comes standard with a built-in C3 input filter, which can directly meet the unrestricted use requirements of Class II industrial environments, avoiding electromagnetic interference problems caused by improper selection and installation of external filters from the source, and ensuring stable operation of equipment in complex industrial environments. At the same time, the product adopts a riveting connection structure, combined with hot-dip galvanized sheet material, which not only improves the corrosion resistance of the equipment, but also ensures reliable grounding, further optimizing the EMC performance of the product.

3、 GD200A's comprehensive protection system ensures long-term stable operation of equipment
INVT GD200A frequency converter always regards reliability as the core design criterion of its products. The design of the entire series of products strictly follows EC international standards, and each power segment product has passed CE certification, providing strong guarantee for customers' reliable use. The product adopts a wide voltage range design and supports AC 3PH 380V (-15%)~440V (+10%) grid input, which can perfectly adapt to harsh and fluctuating user grid environments, avoiding equipment shutdown caused by grid fluctuations.
At the same time, the INVT GD200A frequency converter is equipped with more than 30 fault protection functions such as overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, etc., which can accurately record the detailed operation status of the frequency converter during faults and support automatic fault reset function. The product has also passed comprehensive reliability tests such as packaging compression resistance, random vibration, drop, high and low temperature storage, humidity and heat, salt spray, and low air pressure. The entire process from design to production ensures product reliability and can meet the most complex industrial application environment requirements.

4、 GD200A covers all scenarios, empowering energy efficiency upgrades across multiple industries
The INVT GD200A frequency converter, with its comprehensive functional design and full power coverage capability, can be widely adapted to meet the application needs of multiple industries. The product power covers the entire range of 0.75kW~500kW, and the G-type machine and P-type machine are respectively suitable for heavy and light load scenarios, which can be perfectly applied to multiple mainstream industries such as air compressors, petroleum, HVAC water supply, plastic machinery, mining, fans and pumps.
For the specific needs of different industries, INVT GD200A frequency converter also provides corresponding functional solutions, such as built-in dedicated constant pressure water supply function, which can achieve constant pressure variable frequency water supply by matching one frequency converter with multiple water pumps, supporting analog quantity, keyboard input and 485 remote communication control; The full range of products supports both DC bus solutions and DC power supply modes, which can adapt to various industrial scenarios with multiple machine linkage, truly realizing the adaptation of one machine to multiple scenarios, providing core driving support for industrial automation and energy efficiency upgrades in various industries.
