KDYD-GY power frequency overvoltage protection test device is characterized by safety and reliability, easy to use, simple maintenance, mainly used for various electrical products, electrical components, insulation materials and other overvoltage test under the specified voltage

1.Directly set the output voltage through the touch screen button, one key start, automatic completion of the test;
2. during the test, there is an obvious voltage display on the screen, always remind the operator to pay attention to safety;
3.automatic timing function, automatic control, when the voltage automatically rises to the set value, the device automatically starts timing, when the timing time is up, the device automatically returns to zero;
4. manual control mode, this mode is similar to the traditional electric lift/buck mode, the rise/fall is controlled by touching the button, the device automatically determines the upper/lower limit, there is overvoltage protection;
5. the boost speed intelligent control, when the voltage reaches the target voltage 80%, the boost speed will automatically slow down, when the target voltage 90%, the pressure increase speed is further slowed down;
