Hot Sale | Zhengli Fuji MDQ Series Single-Phase Bridge Rectifier Modules: High-Efficiency Upgrade

Currently, Zhengli’s Fuji-spec MDQ150 and MDQ200 single-phase bridge rectifier modules are in high demand. Featuring standardized packaging, robust electrical performance, and high reliability, these modules precisely meet the rectification requirements of industrial power supplies, variable-frequency equipment, and charging stations, providing efficient and stable core solutions for small- and medium-power DC power supply systems.

Designed strictly in accordance with Fujitsu’s standard dimensions, these modules offer strong compatibility and easy installation, allowing them to directly replace imported components of the same specifications. This effectively reduces equipment retrofitting costs and simplifies inventory management. The MDQ150 has a rated current of 150A, while the MDQ200 has a rated current of 200A. Both models utilize high-quality rectifier chips combined with vacuum brazing technology to achieve 2500V AC electrical insulation between the chip and the substrate. This insulation performance meets high-end industry standards, completely eliminating the risk of electrical leakage and ensuring long-term safe operation of equipment.

In terms of performance, the MDQ series offers significant advantages. The modules feature low forward voltage drop, resulting in lower energy consumption and reduced heat generation. With a maximum operating junction temperature of 150°C, they offer excellent temperature resistance and power cycling capability, easily handling harsh operating conditions such as frequent start-stop cycles and load fluctuations. Additionally, they possess robust surge current withstand capability and enhanced short-circuit protection, significantly improving the system’s immunity to interference and extending its service life, perfectly balancing high-efficiency rectification with long-term durability.

Thanks to its compact and lightweight structural design, this series features a small footprint and high thermal efficiency, enabling stable operation without the need for complex cooling components. It is widely used in applications such as DC power supplies for instruments and meters, PWM inverter rectification, DC motor excitation, welding machine power supply, and industrial control switching power supplies. Whether for industrial automation equipment, new energy infrastructure, or general-purpose power conversion devices, the MDQ150 and MDQ200 deliver stable output and reliable quality, helping customers improve system performance and reduce operational and maintenance costs.

As Zhengli’s best-selling products, this series of Fuji-spec rectifier modules precisely meets the market demand for medium-to-high-power single-phase rectifiers through their cost-effectiveness and standardization. They serve as the preferred solution for industrial control, power, and new energy industries to replace imported products and optimize supply chains, helping users build more efficient and stable power conversion systems.
