400 A / 75 mV current shunt — accuracy class 0.5 Key benefits Precise high-current measurement: Converts up to 400 A into a proportional 75 mV signal for straightforward measurement without high-voltage instrumentation. Reliable accuracy: Accuracy class 0.5 provides consistent readings for monitoring and control applications where repeatable current measurement matters. Robust operating range: Specified for use from -40 to 60 C and up to 95% relative humidity at 35 C, suitable for indoor and many outdoor or industrial environments. What it does and why you need it Function: Produces a 75 mV output at the rated 400 A current so standard meters, data loggers or battery monitors that accept a 75 mV input can measure high currents safely and accurately. Problem solved: Eliminates the need to run high-current conductors through measurement instruments and reduces the risk and complexity of direct high-current measurements. Standout feature: Direct 75 mV output at full scale simplifies integration with existing 75 mV based instruments and control systems. Compatibility and performance Compatibility: Works with meters, recorders, battery monitors and control panels designed for a 75 mV shunt input or proportional low-voltage current input. Performance: Accuracy class 0.5 ensures measurements remain within the specified tolerance for reliable monitoring and data collection. Environmental tolerance: Rated for continuous operation from -40 to 60 C and in humid conditions up to 95% RH at 35 C. Practical applications Solar and battery energy systems: Measure charge/discharge currents in large battery banks and inverters where 400 A currents are common. Industrial power monitoring: Track motor, generator or distribution line currents for preventive maintenance and energy management. UPS and backup power systems: Monitor high DC or AC currents feeding critical systems to ensure safe operation and capacity planning.
