Dari Electric recommends for you

Device Features
1)  Automatically find the resonance point, frequency range 20-300Hz, frequency resolution 0.1Hz;
2)  Automatic voltage withstand test, users can set test procedures, the system automatically completes the test process according to the set procedures;
3) Automatically save test data, data query function, query previous test data according to query conditions;
4)  Five protection functions: overvoltage, overcurrent, power failure, flashover and full voltage output protection;
n Overvoltage protection: overvoltage protection value can be manually set; when the output voltage of the whole device reaches the protection setting value, the whole device is automatically cut off;
n Overcurrent protection: overcurrent protection value can be manually set; when the output current of the whole device reaches the protection setting value, the whole device is automatically cut off;
n Breakdown protection: with discharge or flashover protection function, when a ground flashover occurs on the high-voltage side, the whole device is automatically cut off. It will not cause injury to test equipment and personnel, and the electronic components in the variable frequency power supply will not be broken down;
害，变频电源内电子元件不会击穿;
n Power failure protection: after the test power supply is cut off, the device can protect quickly;
n Full voltage output protection: during the voltage regulation process, it is strictly guaranteed that the variable frequency power supply will not output full voltage;
5)  The LCD screen can display the power supply voltage and current; the frequency, voltage, and current of the high-voltage output;
