FL-19 Welding DC Shunt 300A
The FL-19 Welding DC Shunt 300A is purpose-built for heavy-duty welding systems, offering accurate and fast-response current sensing for advanced welding control. It outputs 75mV at 300A with a low resistance value of 0.25mΩ, ensuring precise monitoring with minimal energy loss.
This model is particularly suited for arc welders, pulse welding systems, and multi-process industrial welding stations. Its robust construction features a manganin resistive element with high shock and arc resistance, providing long-term stability under fluctuating high-load currents and intense thermal environments.
Ideal for integration into welder feedback loops and inverter-based controllers, the FL-19 300A shunt supports real-time current waveform capture, arc consistency improvement, and enhanced weld accuracy. Its bolt-on mounting structure allows seamless panel or chassis installation, with optional custom terminal formats.
