NTC open protection is implemented for device safety. When NTC is open, it will cut off GATE output to disable heating, and the LED1 will flash at 1/8 CLK. The device can be used in both 120V and 240V power line supplier, automatically adjusting the heating power according to the power line voltage to avoid heating appliance damage.
