The equipment shall strictly comply with IEC 61000 Electromagnetic Compatibility Standard and YB/T 4300-2012 Large Graphite Electrode for Submerged Arc Furnace. The product has accurate voltage regulation function (output voltage fluctuation ≤ ± 0.5%), current limiting capacity (current deviation ≤ ± 1%), soft start characteristic (reduce starting current impact), over-temperature protection mechanism (automatically cut off power supply in case of abnormal temperature) and fault restart function (support manual/automatic recovery), fully covering the core requirements of industrial heating scene. The non-contact infrared thermometer can be configured to monitor the surface temperature of graphite reactor or heating furnace in real time, and the temperature control accuracy of 0.3% can be achieved by combining exclusive algorithm. Integrating RS485 communication interface, supporting remote adjustment of power and temperature parameters through touch screen or PC terminal, and recording historical data to achieve lake tracking during production. We have a wide range of products, not only thyristor phase controlled rectifier power supply, but also the latest technology silicon carbide modular power supply, with efficiency up to 95% and volume reduction of 60%. Besides, we support the closed-loop control of frequency modulation and power regulation, and support the development of intelligence, green and high precision in the future. This product is widely used in carbon fiber production, graphite reactor heating, nuclear fuel rod graphite cladding sintering, vacuum graphite heating furnace, high-purity graphite roasting, etc.
