Most cars "220V Cooling Fan" control circuit, the positive cooling fan motor has two relays, control the motor at high speed and low speed, "220V Cooling Fan" The difference is that there is only a low speed relay circuit series with a resistor governor limit the current, so that the motor operating current is reduced to reduce speed. Under normal circumstances, when the car "220V Cooling Fan" in low-speed operation mode, the operating current is generally less than 10A, this time the governor will heat resistance, but the temperature is controlled in a safe range.
