Features
1. Similar products are smaller in size, lighter in weight, more aesthetically pleasing, more reliable, easy to operate, fully functional, and convenient for outdoor use.
2. We adopt advanced technology and manufacturing processes, and take the lead in applying the latest PWM intermediate frequency pulse width modulation technology and pulse train logic array modulation. We use high-power IGBT devices and voltage feedback to achieve higher output high voltage stability and smaller ripple coefficient.
3. The main components of the instrument are made of advanced technology imported from countries such as the United States, Germany, and Japan, which are durable and not afraid of continuous short circuit discharge to ground.
4. High precision and accurate measurement. The voltage and current meters are both digital displays with a voltage resolution of 0.1kV and a current resolution of 1uA. The voltage meter on the control box directly displays the voltage value applied to the load test sample without the need for an external voltage divider during use, and the wiring is simple. The instrument has high and low voltage ends for measuring leakage current, and the high voltage end is displayed with a circular shielded digital meter, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.
5. High voltage regulation stability, smooth voltage regulation across the entire range, output voltage regulation using imported single multi turn potentiometers, smooth boosting process, and high regulation accuracy.
6. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and unique disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, ensuring safe operation, and various technical indicators are superior to industry standards.
7. The addition of high-precision 75% VDC-1mA function brings great convenience to the measurement of zinc oxide lightning arresters. A gentle press does not require calculation. There is a 75% voltage function key on the control box of this instrument. During the lightning arrester test, when the current rises to 1000uA, press the 0.75UDC-1mA button. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, immediately return the voltage regulator potentiometer to zero and press the green button to cut off the high voltage and turn off the power switch. Conduct other experiments.
8. The convenient overvoltage setting function adopts a digital dial switch, which can intuitively display the set voltage value, making your operation more flexible. The displayed value is in kV.
9. The double pressure cylinder is developed and produced using American technology, and the intermediate frequency transformer is specially designed by relevant experts to be small in size, large in capacity, strong in overload capacity, and easy to operate and test on site.
10-1. There are four concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder.
10-2. The upper cover of the control box can serve as a windproof base, which can be plugged into the pressure doubling cylinder to enhance its stability.
10-3. The control box has added overvoltage and overcurrent protection lights to improve safety performance.
