INVT GD20 series frequency converter reliability design: rigorous testing to build a long-term operational defense line
1、 International standards and authoritative certifications
The product design of INVT GD20 vector frequency converter strictly follows IEC international standards and has passed CE certification testing. The safety performance, electromagnetic compatibility performance, and electrical performance of the product have reached the international advanced level and can adapt to industrial application standards in various regions around the world. It is worth mentioning that INVT is the first manufacturer in the domestic industrial control industry to obtain the ACT qualification issued by TUV SUD. The test data issued by its laboratory has been officially recognized by TUV SUD in Germany, and the authority and accuracy of the test results have been internationally recognized, providing hardcore support for the product quality of GD20 vector frequency converters.
2、 Full dimensional environmental reliability testing
To ensure that the GD20 vector frequency converter can handle various complex industrial environments with ease, Envision has established a comprehensive reliability testing system and completed rigorous testing and verification of the product in all dimensions. The core testing items include:
Mechanical reliability testing: Complete the full project testing of packaging compression, drop, vibration, impact, etc., to verify the product's resistance to mechanical impact during transportation, installation, and operation;
Climate based environmental reliability testing: Through dozens of tests such as high and low temperature storage and operation, alternating humidity and heat, temperature shock, salt spray, low air pressure, etc., verify the operational stability of the product in harsh environments such as extreme temperature, humidity, corrosion, and high altitude;
Electrical performance reliability testing: Complete full project electrical testing for long-term full load aging, voltage fluctuations, short-circuit protection, overload protection, etc., to verify the electrical reliability of the product during long-term operation.
3、 Precise thermal design and heat dissipation optimization
Thermal design is the core of the long-term reliable operation of frequency converters. The INVT GD20 vector frequency converter introduces advanced thermal simulation technology in the design stage, and all models in the series have completed precise thermal simulation and design. The power components, heat dissipation ducts, and overall temperature rise of the frequency converter have been fully optimized to ensure that the product can maintain a reasonable temperature rise even under full load operation and high temperature environment, avoiding device aging and shutdown problems caused by overheating from the source. At the same time, it is equipped with an independent air duct design and an efficient cooling fan to further improve the heat dissipation efficiency and ensure the stability of the frequency converter's continuous full load operation for 7 × 24 hours.
4、 Full chain service and quality assurance system
In addition to the reliability design of the product itself, INVT also provides a comprehensive full chain service and quality assurance system for GD20 frequency converters. INVT has established over 50 branch offices, 160 joint maintenance centers, and 900 channel partners both domestically and internationally, radiating to more than 200 countries and regions worldwide. It has established a comprehensive sales and service system and can provide users with one-stop pre-sales selection, installation and commissioning, and after-sales maintenance services. The domestic unified service hotline 400-700-9997 responds throughout the entire lifecycle of the GD20 vector frequency converter, providing users with peace of mind and peace of mind.
