| 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. |
