In the era of Industry 4.0, intelligent manufacturing has become the core direction of global manufacturing development.
The essence of intelligent manufacturing is to realize the automation, digitization and intelligence of the production process through the deep integration of information technology and manufacturing technology.
This places unprecedented demands on the accuracy, stability, reliability and service life of industrial equipment.
As the core basic component in industrial control circuits, Huade alloy resistors have become an indispensable “stable cornerstone” of industrial automation equipment due to their excellent performance.
Industrial control equipment usually needs to run continuously for a long time in harsh working environments with high temperature, high load, dust, and strong electromagnetic interference.
Ordinary resistors are prone to performance degradation, resistance drift, and even burnout and failure in this environment, causing equipment shutdown and causing huge economic losses to the company.
Huade alloy resistors use special high-temperature alloy materials and precision sintering processes, with an operating temperature range of – 55°C to + 275°C, and can operate stably for a long time even in a high temperature environment of 150°C.
After 1,000 hours of continuous operation at rated power, the resistance change rate of Huade alloy resistors is less than 0.5%, and the aging rate is less than 0.1%/year, which can meet the service life requirements of industrial equipment for more than ten years.
In industrial automation equipment such as PLC controllers, servo motors, frequency converters, industrial power supplies, and robot controllers, Huade alloy resistors are mainly used for current detection, power current limiting, and voltage dividing.
For example, in frequency converters, Huade alloy resistors accurately detect the operating current of the motor and provide real-time feedback signals to the control chip to achieve precise speed regulation and overload protection of the motor.
When the motor has an overload or short-circuit fault, the current will increase sharply. Huade Alloy Resistor can quickly and accurately detect this change and trigger the protection circuit to act, cut off the power supply, and protect the motor and inverter from damage.
In industrial power supplies, Huade alloy resistors can withstand frequent large current impacts, ensure the stable output of the power system, and provide reliable power supply for the entire industrial control system.
In response to the high-power application requirements in the industrial field, Huade Electronics has specially developed THE series of wide electrode alloy resistors.
This series of products adopts a unique wide electrode structure design, which greatly increases the contact area between the resistor and the PCB board, and significantly improves the heat dissipation efficiency.
The power of THE series can reach up to 36W, which is 12 times that of ordinary 2512 package resistors. It can meet the needs of high-power equipment such as industrial inverters, high-power switching power supplies, and UPS uninterruptible power supplies.
At the same time, the wide electrode structure also enhances welding reliability, reduces equipment failures caused by false welding, and improves the stability of the entire system.
With stable and reliable product quality, complete product line and professional technical support, Huade Alloy Resistors has become a long-term partner of international industrial giants such as Siemens, Schneider, ABB, Mitsubishi, and Omron.
Its products are widely used in many fields such as intelligent manufacturing, industrial robots, rail transportation, power electronics, new energy power generation, etc., providing solid basic component support for the transformation and upgrading of China’s manufacturing industry.
