Dividing line of switch protection controller with ordinary LCD controller
1 watchdog boundary protection can distinguish fault is within or outside the boundary separating from users
Can greatly improve the power supply reliability of the user, to avoid the other fault users affects the normal power supply
2 the built-in ultracapacitors, even after the superior substation break-brake, after delay fault decision limits, can still break-brake time, increase the reliability of the switching action
3 dial the code type protection setting value, can be in the case of no electricity protection setting intuitively set, all the fixed value at a glance, comprehensive visual!!!!!
VS 
Intelligent machines, handheld data can be within the scope of the boundary controller of 30 meters, view the current switch, voltage state, the protection setting value,
And ordinary LCD protection controller is required to climb the column so can view the data, require multiple protection setting operation to read!
