BEP LB-800-50 800A 50mV DC Ammeter Shunt

BEP Marine 800A 50mV DC Ammeter Shunt (LB-800-50)

The BEP LB-800-50 is a heavy-duty, high-precision 800 Amp / 50 Millivolt DC current shunt designed for high-capacity power monitoring systems on commercial marine vessels, large motor yachts, and off-grid renewable energy installations. Installed in-line with main DC positive or negative distribution buses, it converts heavy DC current flow into a proportional low-voltage millivolt signal (0–50 mV) for remote meters, analog ammeters, and digital battery monitors.

Engineered with high-grade Manganin resistive element blades brazed into heavy copper terminal blocks, the LB-800-50 ensures exceptional temperature stability and minimal resistance drift under heavy continuous load. It features dual heavy-duty main terminal studs for large-gauge battery cable lugs and dual sense screw terminals for precise voltage drop detection.

Key Features

• High Continuous Load Capacity: Rated to continuously measure DC currents up to 800 Amperes with high linearity.

• Manganin Alloy Element: Utilizes low temperature coefficient Manganin resistance alloy to prevent thermal drift during high-amp operation.

• Standard 50 mV Scaling: Fully compatible with standard 50 mV full-scale analog panel meters, digital multi-meters, and CZone/BEP digital switching displays.

• Heavy Brass/Copper Terminal Blocks: Solid metal end blocks ensure minimal electrical contact resistance and maximum thermal dissipation.

• Isolated Baseboard Mounting: Non-conductive insulating base allows direct mounting to bulkheads and battery panels without risk of ground shorting.
