Professional products, quality assurance, OSWELL present at exhibitions in Mexico and Brazil
OSWELL will present at the INA PAACE Automechanika in Mexico and the FIEE in Brazil in July.
Quality control is an important part of our packaging and shipping process. We carefully check each shunt product before packaging to ensure that it meets our strict quality standards. During shipping, we track each shipment and provide regular updates to our customers regarding the status and expected delivery date.
How shunts are produced
Shunts are typically made from materials with low resistance, high conductivity, and good stability over time. The most common material used for shunts is manganese-copper (MnCu) alloy, but other materials such as nickel-chromium (NiCr) and copper-nickel (CuNi) alloys are also used depending on the requirements of the application.
what is shunt?
Shunts are a type of resistor that is specifically designed to measure current. They work by creating a voltage drop across the resistor as a result of the current flowing through it. By measuring this voltage drop, we can calculate the current passing through the shunt using Ohm's law (I=V/R).

The larger the series resistance is, the more the short circuit current drops, and the more the filling factor will accordingly; The smaller the shunt resistance, the greater the current, the more the open circuit voltage drops, and the more the fill factor drops.
Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).

Three key parameters of the shunt
The shunt used in the power battery PACK is essentially a resistor to detect the current value flowing. Since the current value is not easy to monitor, most of them are converted into voltage at present, that is, when the current passes, the resistor generates a voltage drop, and the voltage value is detected to calculate the passed current value, which is based on U=IR.
The 7550A is an ammeter with a measurement range from 1µA to 250A. The voltage on the shunt is switched to the internal four-and-a-half-digit AC and DC ammeter directly displayed by the five file-bit buttons and on the external output terminal.
