1、 Overview of DC Voltage Tester:
The SDZF series DC withstand voltage tester, also known as the DC high voltage generator, is produced by Yangzhou Sudian Electric Co., Ltd. This product has high voltage regulation stability, smooth voltage regulation across the entire range, and output voltage regulation using an imported single multi turn potentiometer. The boosting process is smooth, the adjustment accuracy is high, and it is designed with coarse and fine adjustment functions. The voltage regulation accuracy is better than 0.1%, the measurement error of voltage and current is less than 1.0%, and the pulsation factor is better than 0.5%.
2、 Main features of DC voltage tester:
1. The DC voltage tester is smaller in size, lighter in weight, more aesthetically pleasing, more reliable, easy to operate, and fully functional, making it an ideal and reliable product for outdoor use in the new century.
2. Applying PWM high-frequency pulse width modulation technology, pulse train logic array modulation, using high-power IGBT devices, and utilizing high-frequency technology to increase the frequency up to 100kHz, resulting in higher output high voltage stability and smaller ripple coefficient.
3. According to the maintenance free design, the main components 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 0.1uA. 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 terminals for measuring leakage current,
The high-voltage end adopts a circular shielded digital meter display, which is not afraid of discharge shock and has good anti-interference performance, suitable for on-site use.
5. The voltage regulation has high stability and smooth voltage regulation across the entire range. The output voltage regulation adopts an imported single multi turn potentiometer, which ensures a smooth boosting process and high adjustment accuracy. It is also designed with coarse and fine adjustment functions. The voltage regulation accuracy is better than 0.1%, the measurement error of voltage and current is less than 1.0%, and the pulsation factor is better than 0.5%.
6. Negative polarity output, zero start, continuously adjustable, with various protection functions such as overvoltage, overcurrent, return to zero, grounding protection, and * disconnection protection. The automatic protection circuit has strong functions, complete and reliable protection, ensuring safe operation. All technical indicators are superior to industry standards and superior to similar products.
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, the 0.75 button is turned on. At this time, the values displayed on the voltmeter and ammeter are 75% of the data. After completion, the boost knob should be immediately returned to the zero position, and the fine adjustment voltage knob should be returned to the zero position. The green button should be immediately pressed 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. There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder.
