This series of ultra-precision manganese-copper alloy shunts features low thermoelectric potential and low temperature coefficient. With rated currents of 500A and 700A, resistance values of 50μΩ and 100μΩ, and a rated power of 25W, they adopt a four-terminal Kelvin connection and electron beam welding process. Widely applicable to battery management systems, current detection in power electronic equipment, frequency converters, UPS (uninterruptible power supplies), motor control, and electronic load equipment
