In the field of power electronics, there is a growing demand for efficient and reliable components. As the demand for high-power solutions continues to grow, SONHAO Power Electronics rises to the challenge with its innovative range of water-cooled ultra-high power resistors (UEPR). These liquid-cooled resistors are revolutionizing the industry with their advanced materials, patented designs and versatile applications.
The UEPR series of resistors are manufactured from advanced materials with a patented design that completely isolates the resistance from the coolant, providing a lightweight, small, and high-power solution for water-cooling applications. Its revolutionary modular design means they can be strung together in series to meet your power needs. Used in power generation, power transmission, electric transmission and other electrical equipment fields.
Technical characteristics
The use of all-plastic resistance shell and water channel, so that the product has good high pressure resistance and excellent high temperature anti-aging characteristics and acid resistance. Double-sided channel design, so that the water flow without resistance and no dead Angle of the channel, the resistance body design to minimize its inductance and capacitance.Special process installation fixed, so that this product has excellent vibration/shock resistance.
Special meet: miniaturized MW load cabinet resistance
The advantages of water-cooled resistors extend beyond their modular design and advanced materials. These resistors effectively dissipate heat through liquid cooling, providing a more efficient and compact solution compared to traditional air-cooled alternatives. This not only saves valuable space but also helps improve overall system efficiency and reliability.
In short, Songhao Power Electronics Components’ UEPR series of water-cooled ultra-high power resistors is an industry game changer. With advanced materials, patented designs and versatile applications, these resistors provide compelling solutions to the changing needs of high-power applications. As the demand for efficient, reliable power electronic components continues to grow, SONHAO’s commitment to innovation and quality has made them a leader in the field, delivering solutions that power the world’s most critical applications.
