YSB808A high frequency DC high voltage generator is a new generation of portable DC high- voltage generator redesigned and manufactured by our company according to the requirements of Chinese professional standard ZBF24003-90 《General Technical Conditions for Portable DC High Voltage Generator》. It is applicable to DC high voltage test and leakage current test of zinc oxide arresters, power cables, generators, transformers, switches and other equipments in power departments and enterprise power departments. YSB808A high frequency DC high voltage generator meets the technical requirements of national standard and professional standard ZBF24003-90 《General Technical Conditions for Portable DC High Voltage Generator》. It is applicable to field test of various high voltage electrical equipments in electric power departments, zinc oxide arresters, DC withstand voltage test of power cables and leakage test. It also serves as a power source for electrostatic dusting and spraying. YSB808A series high frequency DC high voltage generators adopt pulse width modulation technology, advanced electronic circuits and components, and output can be protected from power grid fluctuations, zero position, overcurrent, breakdown, overvoltage and so on. Regardless of overcurrent, breakdown and overvoltage, protection circuits can operate quickly, and protect equipments & personnel effectively. Its output adopts liquid crystal display, volume and weight are more lighter than original product, and is very suitable for field use. The newly design"0.75U" LCD can display directly and latch 0.75U1mA field test without manual calculation. The advantages for YSB808A high frequency DC high voltage generator are small size, high power, light weight, easy to carry, convenient operation, safe reliability and so on.
