BEP 100A 50mV Ammeter Shunt

BEP 100A 50mV Ammeter Shunt (100A-50MV / 113454)

The BEP 100A-50MV (Catalog SKU: 113454) is a precision marine-grade DC Current Ammeter Shunt designed to enable high-current monitoring across analogue moving-coil panel meters and digital power displays. Placed inline along the main negative DC supply lead, it drops a linear proportional voltage signal of 50 mV at 100 A of current flow (0.5 m Ω internal resistance).

Constructed with high-accuracy brass terminal blocks and manganin resistance element blades, the shunt ensures minimal temperature drift and high measurement accuracy (0.5% Class rating). Built on an insulated phenolic base, it provides electrical isolation from the mounting surface while allowing safe sense-wire routing directly to remote dashboard instruments.

Key Features

• Precision Manganin Resistor Element: Delivers stable 0.5% class accuracy across fluctuating operating temperatures.

• Low-Millivolt Signal Transmission: Converts high DC amperage into a safe 0-50 mV signal for remote monitoring meters.

• Insulated Flame-Retardant Base: Mounts securely to bulkheads while isolating current-carrying studs from vessel grounding.

• Heavy-Duty Brass Connection Blocks: Accepts high-gauge main power cable lugs alongside smaller #8 / M4 sense-wire terminals.

• Universal Meter Compatibility: Fully compatible with BEP analogue meters, digital battery monitors, and standard 50mV full-scale deflection instruments.
