High-Precision Shunt Based Current Sensing Module

The RESI ARCS6918-L050 is a shunt current sensing module designed for accurate high-current measurement in power electronic systems. It uses a Mn-Cu alloy resistive element to provide stable performance with low thermal EMF and low inductance. With a resistance of 50µΩ, rated current of 700A and power rating of 25W, the module enables accurate current sensing with minimal power loss. A four-terminal Kelvin connection ensures precise voltage measurement by eliminating lead resistance effects. Manufactured using an electron beam soldering process, the module offers strong mechanical reliability. It operates across -55°C to +175°C and is suitable for automotive and industrial environments.
