CG DC Shunt FAQs
Answers to common questions about CG DC shunts and their applications.
A1: A DC shunt is a low-resistance precision resistor used to measure direct current (DC). When current flows through the shunt, it generates a small voltage drop that can be measured to calculate the current value accurately.
A2: CG shunts offer standard accuracy within ±0.1%. For applications requiring higher precision, we also provide customized solutions with accuracy up to ±0.01%.
A3: Yes, we offer fully customized shunts, including adjustments to current and voltage range, resistance, size, mounting style, logo, and accuracy grade to meet your exact application requirements.
A4: Our products comply with international standards and are certified by ISO9001, CE, and UL, ensuring safety, reliability, and consistent quality.
A5: CG shunts are widely used in Battery Management Systems (BMS), Electric Vehicles, Solar Energy Systems, UPS power supplies, and other industrial and high-current applications.
A6: CG DC shunts are made with high-quality manganin or copper alloy elements, ensuring stable resistance, excellent thermal performance, and long-term reliability.
