A precision current shunt designed for heavy-duty DC ammeter applications, providing a calibrated 75mV voltage drop at exactly 50 Amps. Featuring robust, welded brass terminals, this shunt is built for direct panel or bus bar mounting to accurately measure current in high-power systems like solar charge controllers, battery banks, industrial machinery, and EV charging stations. Its fundamental 1.5 mΩ resistance enables safe, low-loss monitoring and control.
Key Features & Benefits
-
Calibrated for Direct Meter Reading: Delivers a precise 75mV signal at its rated 50A, allowing for direct connection to 75mV analog meters or scaling for digital controllers without complex calculations.
-
High-Power, Low-Loss Design: Engineered to handle 50 Amps continuously with minimal self-heating and power loss, maximizing system efficiency and reliability.
-
Robust Construction for Harsh Environments: Built with a stable manganin alloy strip and heavy-duty terminals to withstand vibration, thermal cycling, and demanding industrial use.
-
Easy Integration: Standard brass terminals (typically M6 or M8 studs) allow for secure, high-current connections directly to bus bars or heavy-gauge cable lugs.
-
Essential Protection & Monitoring: A critical component for building accurate ammeter circuits, providing the feedback needed for overload protection, charge control, and system diagnostics.
