FL-15 Baseboard Shunt

The FL-15 type shunt is an improved version based on the American shunt design. It is widely used to extend the current measurement range of instruments. The product includes fixed-value shunts and precision alloy resistors, both of which can be applied in communication systems, electronic devices, and power circuits for automation control, serving as current limiting and current balancing sampling detectors.

To ensure high-quality products for customers, the company selects premium manganese-copper alloy sheets. The product utilizes copper-silver-phosphorus solder, resistance contact welding, and fusion welding to ensure reliable processing technology. Each product undergoes rigorous testing and screening before leaving the factory.
