EAK Liquid-Cooled Resistor: A Game-Changer for High-Power Applications

In the realm of high-power electrical systems, managing heat and ensuring reliability are paramount. This is where liquid-cooled resistors come into play, and EAK's latest design is setting new standards in the industry. Whether it's for electric/hybrid aircraft ground testing, shipboard integrated power system testing, or even directed energy weapon test benches, the EAK liquid-cooled resistor is engineered to handle the most demanding applications.
Cutting-Edge Design for Extreme Conditions
EAK's liquid-cooled resistor is a marvel of modern engineering. It features a wide resistance range from 10 milliohms to 32 ohms, with precision levels between 1% and 10%. This wide range and precision make it highly versatile for various applications. Moreover, its temperature coefficient can be as low as 25 PPM, ensuring stable performance even under varying temperature conditions.
The resistor incorporates advanced ceramic insulation, which guarantees an insulation voltage of over 1500V. This is crucial for maintaining safety and reliability in high-voltage environments. Additionally, EAK employs state-of-the-art welding techniques to prevent any liquid leakage, a critical feature for maintaining the integrity of the system.
One of the standout features of this resistor is its ultra-high precision, non-inductive resistor core design. This, combined with an integrated packaging technology, ensures that the resistor can withstand harsh vibration environments, making it highly durable and reliable.
High-Power Density and Compact Design
When it comes to high-power applications, space and weight are often critical factors. EAK's liquid-cooled resistor offers a high power density solution that is significantly lighter than traditional air-cooled alternatives. This is particularly advantageous in applications like electric/hybrid aircraft ground testing and shipboard integrated power system testing, where weight reduction is essential.
The ability to achieve hydro-electric separation is another key benefit of this design. This ensures excellent insulation and electrical performance reliability. A single resistor can handle two 10kW resistors in series or parallel, making it highly efficient in terms of power handling capability.
Applications Across Multiple Industries
Electric/Hybrid Aircraft Ground Testing
Testing large power aviation motors and electric propulsion systems requires the ability to absorb megawatt-level power. EAK's liquid-cooled resistor is perfectly suited for this task. It can handle ultra-high currents of up to 1000A and ultra-high working voltages of up to 110kV. This makes it an ideal solution for the rigorous demands of electric/hybrid aircraft ground testing.
Shipboard Integrated Power System Testing
Similar to aviation applications, shipboard integrated power systems require robust testing of high-power propulsion motors and weapon system power sources. The ability to absorb ultra-high power loads is crucial, and EAK's liquid-cooled resistor provides a reliable and efficient solution. Its water-cooled design is not only effective in managing heat but also ensures that the system remains lightweight and compact.
Directed Energy Weapon Test Benches
Directed energy weapons, such as lasers or microwave sources, pose significant challenges in terms of energy absorption and thermal management. EAK's liquid-cooled resistor can act as a key component of the test load, providing the necessary power absorption and heat dissipation capabilities.
Conclusion
EAK's liquid-cooled resistor is a testament to the company's commitment to innovation and excellence. With its wide resistance range, high precision, low temperature coefficient, and advanced insulation and packaging technologies, it is designed to handle the most demanding high-power applications. Whether it's in the aerospace, maritime, or defense sectors, this resistor offers a reliable, efficient, and high-performance solution. As the demand for high-power density and compact design continues to grow, EAK's liquid-cooled resistor is poised to play a crucial role in the future of electrical systems testing and operation.
