Our company's new generation of ultra-low frequency high voltage generator is the core product of independent research and development, using 7 inch touch screen, imported high-speed AD acquisition circuit, and new production technology. It improves the quality and stability of the instrument, reduces the volume and weight of the equipment, is simple to operate, and overcomes many shortcomings of similar domestic products (see Table 1). The mechanical booster has the disadvantages of short service life, high failure rate and large volume that are more cost-effective than those of similar imported products. Compared with other voltage test equipment, 0.1Hz ultra-low frequency has many advantages

High degree of intelligence: the use of digital frequency conversion technology, microcomputer control, boost, buck, measurement and other test processes are fully automated.
Easy operation: simple wiring, 7 inch LCD touch screen, easy operation, friendly human-computer interaction.
Comprehensive protection: multiple protection (overvoltage protection, high and low voltage sidecurrent protection), rapid action (action time ≤10ms), safe and reliable instrument.
Safe and reliable: low voltage connection between controller and high voltage generator, photoelectric control, safe and reliable use.
The high and low voltage closed loop negative feedback control circuit is adopted, and the output has no capacity rise effect.
Accurate sampling: High-voltage current and voltage data are obtained directly through high-voltage side sampling, so the data is true and accurate.
Complete configuration: 7-inch capacitive touch screen, LCD Chinese character display, automatic storage, automatic printing.
Wide test range: 0.1Hz, 0.05Hz and 0.02Hz multi-frequency selection, large test range.
Easy to carry: The instrument is small in size and light in weight, which is very conducive to outdoor work.

Power supply: 220V±5%, 50±2Hz. Note: If the portable generator is used, the output voltage and frequency of the generator are required to be stable (generally, the power is greater than 3kW, the frequency is 50Hz, and the voltage is 220V±5%).
