Device Functions | Precision Adjustment | The voltage regulator can accommodate an input voltage of 380V ±15% and ensure that the output voltage accuracy is maintained within 372V to 388V. |
Quantitative Compensation | When the input voltage remains in a prolonged feed or overflow state, the voltage regulator compensates quantitatively by 15%. If the grid voltage is too low or too high, the power of the voltage regulator should be appropriately increased or decreased to meet the actual power demand. | |
Overvoltage & Undervoltage Protection | When the input voltage exceeds the overvoltage or undervoltage limits of the regulator, the device automatically protects itself by cutting off the output voltage. | |
Short Circuit Protection | In the event of a load short circuit, the device can automatically disconnect the power within the specified time. | |
Limit Protection | If the brush operation exceeds the designated area, automatic adjustment will be terminated. | |
True RMS Sampling Circuit Control | High accuracy, good sensitivity, fast measurement rate, and excellent frequency characteristics. It has high input impedance, low output impedance, a wide power supply range, and low power consumption. | |
