Schneider Electric releases the all-new generation of medium voltage frequency converters Altivar 1200C-S series
With the deepening of new industrialization, the transformation and upgrading towards high-end, intelligent, and green industries is becoming a powerful engine driving the high-quality development of the manufacturing industry. In this context, the recently released “Opinions on Accelerating the Comprehensive Green Transformation of Economic and Social Development” proposes to vigorously promote the green and low-carbon transformation of industries such as steel, non-ferrous metals, petrochemicals, and chemicals, and promote energy-saving, low-carbon, and clean production technology and equipment. In the industrial field, medium voltage frequency converters are widely used as electrical energy control devices for driving and controlling large equipment. Their reliability, flexibility, and level of intelligence are closely related to enterprise production safety, efficiency, and energy consumption. Facing the trend of green and low-carbon transformation, more and more industrial enterprises hope to leverage high-end production equipment and facilities to further release advanced production capacity and enhance competitiveness, bringing more green benefits.

Yu Xin Enlightenment, Intelligent Stability Gain
Based on the core demand of high-end medium voltage variable frequency control for enterprises in the oil and gas chemical, mining, metallurgy, municipal and other industries, Schneider Electric has innovatively created the medium voltage variable frequency ATV1200C-S series on the basis of the original ATV1200C series products. With the reliability upgrade of all elements, full-scale optimization design, and intelligent application support, it can help users improve space utilization and operational efficiency, optimize total cost of ownership, and bring three major values of reliability upgrade (Strong), flexibility and ease of use (Small), and intelligent efficiency improvement (Smart), empowering enterprises to continuously create profits.

Reliable upgrade: The medium voltage frequency converter ATV1200C-S achieves reliable upgrade of all elements by adopting more advanced drive control technology and power electronic devices, which can effectively improve the stability of equipment operation. Among them,Its standard power unit adopts the new generation IGBT module packaging technology (with built-in temperature measurement module), and equipment with 80A and below integrates a “rectifier bridge+inverter bridge” integrated structure, and uses long-life metal film capacitors, which are conducive to green waste disposal while ensuring circuit safety. With the high integration PCBA design, the overall electrical reliability is achieved;

Sealed casting voltage detection devices and ceramic/epoxy encapsulated bypass contactors have higher insulation strength and stronger environmental adaptability, which can meet the needs of more industrial environments;

With the efficient air duct design, its convective heat transfer efficiency has been increased by an average of 30%, and the noise level has also been significantly reduced;
Configurable power unit bypass, system bypass, high and low voltage ride through functions, as well as dual machine hot standby solutions, make the equipment more available and effectively reduce unplanned downtime losses;

Standard frequency conversion dedicated multi voltage graded protection uninterruptible power supply, providing up to 30 minutes of control power support capability
The entire series of products continues the high overload capacity of the previous generation (120% overload for 1 minute/10 minutes);
By combining phase-shifting multi winding transformers and multi pulse rectification technology, the harmonic current on the grid side has been effectively reduced; Multi level output drive motors do not require additional installation of sine filters, saving costs for enterprises.

Flexible and easy to use: Based on full-size optimized design, the medium voltage frequency converter ATV1200C-S can help enterprises save factory construction costs, reduce on-site installation and wiring time, and facilitate personnel operation and maintenance, helping to optimize the economic efficiency of project investment. Among them,
Based on the new generation of power electronic devices and innovative structural design, the whole machine can save 25% to 50% of the floor area, helping enterprises improve space utilization while avoiding additional factory investment;

The low-power models (10kV/2500kW, 6kV/1600kW and below) adopt an integrated cabinet, which can be equipped with a manual bypass system, greatly reducing on-site installation and wiring time;

The power unit adopts ergonomic design, which not only creates a smaller volume, but also provides high convenience for personnel operation and maintenance;
Rich communication extensions can be configured for easy integration and use, while the 10 inch HMI interface based on professional UI/UX design is simple and easy to operate, enhancing the user experience.

Intelligent efficiency enhancement: With the support of intelligent applications, it covers equipment status monitoring, diagnosis, and operation and maintenance of medium voltage frequency converter ATV1200C-S. Among them,

The fault recording function can record key information before and after the fault occurs, helping operation and maintenance personnel quickly locate the cause of the fault and quickly restore equipment operation;
Support real-time display of DC bus voltage and power unit temperature, and monitor the health status of capacitors and IGBTs;
Environmental monitoring and automatic adjustment function, which can monitor real-time temperature and humidity data inside the cabinet and equipment operation status, and automatically start and stop the heater to improve the operating environment and reduce equipment failure rate;

Relying on the digital equipment management platform, operators can monitor the real-time trend of on-site data changes, control the health status of equipment, and update maintenance plans in a timely manner. This not only reduces unplanned downtime losses but also maximizes production continuity.

In addition, Schneider Electric relies on its deep accumulation in the field of medium voltage frequency converters to provide full lifecycle services covering the ATV1200C-S medium voltage frequency converter from project requirement research, scheme planning, design deployment, installation and commissioning, to spare parts, maintenance, upkeep, training, renovation, and replacement. Its service team has obtained ISO9001 certification, and the average on-site service life of engineers exceeds 15 years. It is distributed in multiple partner maintenance stations in Central, North, and East China, which can timely meet the service needs of enterprises in various regions. At the same time, Schneider Electric’s remote connection expert service center can also provide proactive digital operation and maintenance, remote fault diagnosis and handling services, and has created AI robots to provide 7 * 24-hour online support, ensuring timely response to user needs anytime, anywhere.
