KGFB-320A/400V Output Voltage: 0~400VDC, Output Current: 0~320A
The rectifier of this project is used for electrophoretic spraying, according to the customer’s usage environment and requirements, it is more suitable to adopt SCR design for high voltage, with the top air outlet to reduce the environmental dust into the rectifier and improve the power supply resistance. It has perfect protection functions such as phase failure, over-voltage, over-current, overheating, short circuit, etc. Meanwhile, it adopts unique sealing and sealing channel design to ensure that the equipment can work for a long time under the harsh environment with full load.
According to the electrophoresis process, the DC output is equipped with filter reactor and capacitor, so that the ripple coefficient index reaches the requirement of painting process, and the voltage of Tiven wave can make the paint film on the metal surface with dense structure, even thickness, smooth surface and strong adhesion.

TBSA-±30V/1200A Output current: 0~1200A; Output voltage: 0~±30V
Case introduction:
Four units of ±30V 1200A water treatment electrolysis rectifiers exported to Saudi Arabia, customer feedback rectifiers are on the stable operation and good performance, the energy efficient design not only saves costs, but also environment friendly. According to customer requirements, the rectifier adopt polarity reverse design, so the voltage can be switched in different processes. Above is the field application diagram sent by the customer, we are negotiating new project cooperation.
Liyuan self-developed wastewater treatment power supply can be widely used in various wastewater treatment processes, such as electrocoagulation of electroplating wastewater, electroadsorption, micro-electrolysis technology, and the removal of heavy metals electrolytic precipitation or floating, membrane electrolysis, electrodialysis and ion exchange method.
Based on the richness experiences and advanced technology, we have designed a rectifier as per customer’s specifications, Voltage and current can be adjusted independently, power supply can be displayed and controlled in the machine, or remote PLC display and control, at the same time with soft start ruanting function, soft start time and soft stop time can be set in the field cabinet. This rectifier largely improve the efficiency and save energy,better removal of all kinds of metal ions in the wastewater, so that the wastewater is purified.

TDFB-50V/1000A Output current: 0~1000A; Output voltage: 0~50V
According to customer’s requirements, they need a rectifier for water-electrolytic hydrogen making equipment. A common water electrolysis technique involves putting electrolytic water into a stack composed of catalytic cells and extracting hydrogen through a chemical reaction with electricity. Catalysts are connected to a power source to decompose water into oxygen and hydrogen gas and are normally made from expensive metals such as platinum or iridium.
The TB series synchronous rectifier power supply independently developed by Liyuan is more energy efficient stable in output performance. Made of the most energy-saving high-frequency MOSFET switching power supply, Liyuan third generation of new energy-saving MOSFET switching power supply, using synchronous rectifier MOS tube imported from the United States, Its voltage drop is only 0.IV, 0.6V lower than that of the ordinary second-generation HIGH-FREQUENCY switching power diode 0.7V, high current parallel structure and patented transformer design, efficiency can be up to 94% or more. This type of power supply has been used in many large projects at home and abroad for many years, energy-saving effect is obvious, and stable and reliable, It has been well received by many users.
