Modular water treatment power supply is one of the latest research and development products of Tongke Electric. It uses a touch screen to control the output voltage and current of the power supply, with simple operation and convenient use; High power, able to meet the operational requirements of sewage treatment equipment. The main transformer of this power supply is an efficient and energy-saving transformer independently developed by Tongke Electric. It uses nanocrystalline soft magnetic materials as the main transformer core, with a large over current area, good cooling effect, excellent coupling, and low operating losses, ensuring the service life of the power supply; The main power component of the power supply is a high-power original imported Infineon insulated gate bipolar transistor IGBT module, with high-quality material selection to ensure quality. The output mode is full bridge full wave output, PWM pulse width modulation technology, stable performance, long service life, and reliable process technology. Choose the same brand as the manufacturer of sewage treatment power supply!
This product consists of multiple sets of high-frequency inverter rectifier unit modules. A single set of inverter unit adopts a high-frequency full bridge soft switching type, and the rectifier unit adopts a full wave rectification method. The high-frequency filtering reactor filters the output ripple coefficient to below 1% under rated load. The power supply has a constant voltage and stable current output control function, and the touch screen interface is controlled through human-machine dialogue. The system protection function is complete, and the main controller adopts our company's independently developed pulse width modulation circuit, which has high control accuracy and anti-interference strength. The digital circuit consists of a PLC module and a touch screen. The system has complete protection functions, strong anti-interference ability, and high reliability. Simple operation, user-friendly design, high degree of automation, power supply design and manufacturing follow IEC international electrical technical standards and national industry technical standards.
This sewage treatment power supply equipment can be widely used for the treatment of various industrial wastewater, agricultural wastewater, medical and domestic wastewater, electrolytic wastewater (i.e. used to recover recyclable metal ions from wastewater or treat organic substances through electrolysis), and so on.
