Protection
 

Over and under voltage protection	When the input voltage exceeds the voltage regulator's over-voltage or under-voltage value, the equipment will automatically protect the no-voltage output.
Over current protection	When the current exceeds the rated value, the input is automatically cut off.
Overload, short circuit protection	When the load exceeds the specified overload capacity or short circuit of the equipment, the power supply can be automatically cut off within the specified time.
Limit protection	When the brush operation exceeds the area, the adjustment is automatically terminated.
Mains bypass function	When the voltage stabilizer needs maintenance or malfunctions, the manual  switch can be switched to supply power in a direct connection state.
True effective sampling circuit control	High accuracy, good sensitivity, good measurement rate and frequency characteristics, high input impedance, low output impedance, wide power  supply range and low power consumption.
Back to middle function	When the sampling voltage is lower than the lower limit reference voltage or higher than the upper limit reference voltage, the brush will  automatically return to the center.
