2、 Product Features

1Smaller in size, lighter in weight, more aesthetically pleasing, more reliable, easy to operate, fully functional, and convenient for outdoor use, it is an ideal and reliable product for the new century.

2Using excellent technology and craftsmanship for manufacturing and applicationPWMHigh frequency pulse width modulation technology, pulse train logic array modulation, using high-powerIGBTDevice, utilizing high-frequency technology to increase frequency, with frequencies up to100kHzThus, the output high voltage stability is higher and the ripple coefficient is smaller.

3According to the maintenance free design, the main components are made of imported components with excellent technology from countries such as the United States, Germany, and Japan, which are durable and not afraid of continuous short circuit discharge to ground.

4High precision and accurate measurement. The voltage and current meters are both digital displays, with a voltage resolution of0.1kVThe current resolution is0.1uAThe voltmeter 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.

5High voltage regulation stability, smooth voltage regulation across the entire range, and output voltage regulation using imported single multi turn potentiometers,

The boosting process is smooth, with high adjustment accuracy, and is designed with coarse and fine adjustment functions. Voltage regulation accuracy is better than0.1%The measurement error of voltage and current is less than1%The pulsation factor is better than0.5%.

6Negative 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.

7Added high precision75%VDC-1mAThe function of zinc oxide lightning arrester measurement brings great convenience. A gentle press does not require calculation. There are on the control box of this instrument75%The voltage function key, when conducting lightning arrester tests, when the current rises to1000uAOpen it at the right time0.75The button displays the values on the voltmeter and ammeter75%After completing the data, 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.

8The 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 unit iskV.

9The double pressure cylinder can be divided into sections for on-site use, which is flexible and convenient. It can be used for multiple purposes and is economical.

10There are three concealed support feet at the bottom, which increase the stability of the pressure doubling cylinder.
