Products Description
The Manganin Shunt with 100A for Single Phase Meter is a precision shunt component used in power magnetic latching relays and smart energy metering systems. It is formed by electron beam welding of conductive copper and resistive manganese copper materials to create a composite strip with stable resistance, which is then processed through precision stamping, heat treatment, and ultrasonic cleaning.
In new energy power distribution systems, smart meters, energy storage metering equipment, and power electronic control modules, magnetic latching relays require stable current sensing elements to achieve load on/off control, energy metering feedback, and system protection. This type of EBW Manganese Copper Shunt for Relay serves as a key internal conductive and sampling component, providing a reliable basis for current detection in the system by precisely controlling the resistance value.
Main Product Features and Functions
Current-Voltage Conversion
The Electron Beam Welding Manganin Shunt utilizes the known precise resistance value of the manganese copper section to convert the 100A main circuit current into a mV-level differential voltage signal for metering chip acquisition.
Temperature Drift Compensation Matching
The extremely low TCR characteristics of the 6J13 alloy ensure that the sampling signal remains linear across the entire temperature range, providing a stable reference for the system's temperature compensation algorithm.
High Current Withstand and Heat Dissipation
The copper conductor areas at both ends of the Manganin Shunt Resistor for Electrical Meter provide a low thermal resistance path, quickly conducting Joule heat away from the manganese copper sampling area, reducing the impact of local temperature rise on the resistance value.
Automated Assembly Compatibility
The EBW Manganese Copper Shunt for Relay, precision stamped and deburred, ensures good dimensional consistency, making it suitable for automated placement, wave soldering, or laser soldering assembly lines.
Product Details and Features
The electron beam laser welding interface is flat, free of weld beads and cold solder joints. The welding area of the Maganin Shunt Resistor Shunt does not produce large-sized grains, avoiding localized heat generation.
The stamped edges are smooth and burr-free, and ultrasonic cleaning thoroughly removes processing oil and metal debris, preventing the risk of micro-short circuits in the Manganin Shunt for Single Phase after assembly.
The heat treatment process releases stamping internal stress, making the product less prone to deformation during long-term operation. Terminal hole dimensions remain stable over time, facilitating automated assembly.
The conductive terminal layout of the Maganin Copper Shunt for Electronics Energy Meter is optimized to reduce the skin effect under high current conditions and even out device temperature distribution.
Frequently Asked Questions
Does this shunt support customized shape and structure?
Yes. We can adjust the terminal shape and hole layout according to the customer's magnetic latching relay internal cavity drawings, providing customized development services for the Maganin Copper Shunt for Electronics Energy Meter, which can be used for rapid prototyping during the prototype stage.
Can the resistance value of the Shunt Resistor Of Electricity Meter be adjusted according to requirements?
The resistance value is determined by the size and thickness of the manganin copper region. Within the rated current framework, the sampling area specifications can be adjusted to achieve the target resistance value, and corresponding samples are provided for verification.
Will the electron beam weld of the Manganin Shunt Resistor experience fatigue failure during long-term use?
Our company places the weld in a non-stress concentration area during the weld design phase and optimizes the transition zone structure through thermal cycling finite element analysis. Combined with subsequent stress-relief heat treatment, no cases of weld fatigue-induced failure have been observed in actual applications.
Is the tin plating on the copper ends of the Electric Current Measure Manganin Shunt fully covered or selectively plated?
Selective tin plating covers only the copper terminal connection area. The manganin copper sampling area is not plated to avoid interference from the plating metal on the precision resistance value.
