ZGS-Z Intelligent DC High Voltage Generator
Products Characteristics
1.ZGS-Z series DC high voltage test set adopts the intermediate frequency doubler circuit, first to apply the latest PWM technology and high-power IGBT device. And according to the theory of electromagnetic compatibility, the use of special shielding, isolation and grounding and other measures. The DC high voltage test set to achieve a high quality, portable and can withstand the rated voltage discharge without damage.
2.It is used the modern single-chip microcomputer technology, the LCD display is used to replace the traditional meter and dial switch. it use the voltage feedback makes the voltage stability greatly improved. We specially designed 0.75UDC-1mA function to test Zinc Oxide Surge Arrester. In order to ensure the instrument is small in size, light weight, easy to carry, the instrument operating frequency is more than 30Hz.
3.We use high technical components from America and Japanese, and the international series chassis are made by Germany, which make it be practical and beautiful.
4.The multi voltage barrel is developed with Germany technology, medium frequency transformer is specially designed by our experts, with small size and large capacity. The foundation of multi voltage barrel is designed like the shape △- Y, it means when it is packed into the box, the foundation will shrink into triangle △, when you use the instrument, it will expand into the shape Y, that make the instrument more stable and convenient.
