DC High Voltage Generator

 Technical Conditions

1) Power supply: AC220V±10%, 50Hz±1%

2) Output voltage indication accuracy: <1 level

3) Output current indication accuracy: <1 level

4) Ripple coefficient: ≤0.5%

5) 0.75 times output voltage indication accuracy: <1 level, with latch

Protection Functions

1) Internal overvoltage protection, internal overcurrent protection

2) External overvoltage protection (protection voltage can be set), external overcurrent protection or breakdown protection

3) Internal power protection

4) Non-zero start protection

1) Overvoltage protection

During the test, if no setting is required, turn the voltage setting knob clockwise to the maximum. At this time, overvoltage protection will act when the voltage exceeds the rated output voltage, and the overvoltage protection indicator light (yellow) will be on. If you need to set the overvoltage protection value, before the test, you can first not connect the test object, turn the voltage setting knob clockwise to the maximum, then increase the voltage to the required voltage value according to the above operation process, and then turn the voltage setting knob counterclockwise to the overvoltage protection value and the overvoltage protection indicator light (yellow) will be on. At this time, the overvoltage protection value is set. Then turn off the power switch, use a grounding rod to discharge the high voltage to ground, connect the test object and conduct the test. At this time, if the test voltage exceeds the set value, the high voltage will be automatically cut off and the overvoltage protection will act.

(2) Overcurrent protection

During the test, if no setting is required, turn the current setting knob clockwise to the maximum. At this time, overcurrent protection will act when the current exceeds the rated output current, and the overcurrent protection indicator light (yellow) will be on. If you need to set the overcurrent protection value, before the test, you can first connect the test object, turn the current setting knob clockwise to the maximum, and then follow the above.
