Efficient and stable, excellent output: adopting high-frequency voltage doubling circuit, PWM pulse width modulation technology, and voltage current dual loop feedback technology to ensure high output voltage stability and low ripple. Full range smooth voltage regulation, high output voltage accuracy, meeting various high-voltage testing needs.
Comprehensive protection, safe and reliable: It has multiple protection functions such as zero protection, overvoltage protection, overcurrent protection, and breakdown protection. The protection circuit uses nanosecond level dedicated sensors, which act quickly and reliably, effectively ensuring personal and equipment safety.
Intelligent operation, one click testing: adding an intelligent high-precision 0.75U function button, one click operation can automatically switch the voltage and current to 0.75U state, especially suitable for testing zinc oxide lightning arresters, simplifying the operation process and improving work efficiency.
Integrated design, easy to carry: Adopting an integrated design scheme, the host and pressure doubler are integrated into one chassis, with small size and light weight, making it easy to carry and operate on site. At the same time, the outer surface of the pressure doubling cylinder is coated with special insulation material, which has good electrical performance and strong moisture resistance.
Accurate measurement and intuitive data: Digital voltmeters and ammeters can accurately display output voltage and current values, allowing users to intuitively understand the testing status. In addition, the device also supports data storage and export functions, making it convenient for users to conduct subsequent data analysis and processing.
