Note: The 10A version is on board with low-temperature drift alloy resistance shunt, can be directly connected. The 100A version needs to be connected in parallel with 50A 75mV shunt for normal use. Without the shunt, the current cannot be measured, the shunt needs to be prepared by oneself. The 100A version needs to be connected in parallel with a 100A 75mV shunt for normal use. Without the shunt, the current cannot be measured, the shunt needs to be prepared by oneself.
