Output status indication signal

--

When the output status indicator light (green LED) is on, it means that the product works normally, and the input current of the busbar does not exceed its bearing capacity;

When the output status indicator light is off, it indicates that the product is not working properly or the input current value of the busbar is beyond its capacity.
