High-Precision Murata Current Sensors & Shunts for Off-Grid Power

When building a reliable off-grid power system for your caravan, motorhome, or marine vessel, precision is critical. Our collection of Murata current sensor shunts provides the exact measurements your electrical system requires to function safely and efficiently. Designed for rigorous mobile and stationary applications, a Murata 200A 50mV shunt is a vital component for any advanced power setup, ensuring your control modules receive highly accurate current data.

Why Choose a Murata BMS Current Sensor Shunt?

A shunt measures the voltage drop across a known resistance to calculate the exact current flowing in and out of your battery bank. If your readings are inaccurate, your state of charge (SOC) will drift, potentially leaving you without power when you need it most in remote Australian locations. Murata components are globally recognised for their ultra-durable construction, low thermal drift, and exacting tolerances, making them an excellent choice for demanding mobile environments.

Pairing a high-quality shunt with your monitoring equipment ensures that your Lithium Battery Management System (BMS) can accurately protect your battery bank from overcurrent events and deep discharging, significantly extending the lifespan of your investment.

Key Features of Murata Shunts

• Precise 50mV Drop: Delivers exactly 50mV at a 200A load, providing your Battery Monitoring Systems with reliable, high-resolution data.
• Ultra-Durable Build: Constructed to withstand the continuous vibrations and heavy impacts typical of 4WD trails and harsh marine conditions.
• Low Thermal Resistance: Maintains high accuracy even when operating temperatures fluctuate inside a confined battery box or canopy.
• Straightforward Integration: Features robust standard terminal posts, making it simple to attach heavy-duty Cable Lugs for secure, low-resistance electrical connections.

Common Use Cases

Murata shunts are trusted across a wide range of mobile and stationary power applications where precise current tracking is non-negotiable:

• Caravan and RV: Accurately track power usage from 12V appliances to ensure you never wake up to a flat battery on an unpowered site.
• 4WD and Truck: Monitor high-draw accessories and charging inputs in rugged, vibration-heavy off-road touring setups.
• Marine and Boats: Provide essential current data for house battery banks on the water, where reliable power is a matter of safety and comfort.
• Off-Grid and Tiny Home: Deliver crucial energy flow metrics to large-scale inverters and solar arrays for continuous, uninterrupted living in commercial or residential settings.

Wiring and System Integration

Installing a current sensor shunt correctly is paramount for accurate data. The shunt must be the very first component connected to the main negative terminal of your battery bank. All system loads and charging sources must pass through the shunt. Bypassing it with even a single accessory will result in inaccurate SOC readings.
