Ensure tight contact and large contact area between the shunt copper head and the busbar. Increase busbar size and ensure surface cleanliness where possible. Recommended working current should not exceed 2/3 of the rated current under normal application. Derate usage in ambient temperatures above +40. Cooling methods such as air/water cooling, increasing physical size, or installing heatsinks can be used to reduce working temperature. Wear gloves during installation to prevent oil contamination. Busbar surfaces should be flat and smooth, with nickel or tin plating recommended to reduce contact resistance. Recommended installation torque: M3: 0.4~0.8 N.m, M8: 10~15 N.m.
Store in a temperature of +5 to +35, humidity <60% RH, avoiding direct sunlight and harmful gases. Store in a clean, dry environment. Use dedicated gloves when handling to minimize surface oxidation. Minimum storage life of 1 year under specified conditions.
Minimum packaging is 1 unit. Vacuum sealed packaging internally, with a custom outer box.
Free customized tuning service to optimize detection accuracy for specific application scenarios. Involves precisely adjusting resistance to balance surface temperature at different current loads. Requires customer to provide data including minimum/maximum working current, current curve, product name, location, design life, temperature range, installation method, and cooling conditions. Each customized part receives a unique identification code and a complete factory test report.
