GDVLF series 0. 1Hz program-controlled ultra-low-frequency high-voltage generator combines modern digital frequency conversion advanced technology, adopts microcomputer control, and automatically boosts, depressurizes, measures and protects, and can be manually intervened in the process of automatic boosting. Because it is fully electronic, small in size and light in weight, the large-screen liquid crystal display is clear and intuitive, and it can display output waveforms and printer output test reports. The design index completely conforms to the power industry standard "General technical conditions for special test instruments for power equipment Part 4: General technical conditions for ultra-low frequency high voltage generators", and it is very convenient to use. At present, mechanical modulation and demodulation are used to generate ultra-low frequency signals at home and abroad, so there are some problems such as nonstandard sine wave waveform, large measurement error, high-voltage partial spark discharge, large equipment volume, and high-power and high-voltage resistors are needed for sine wave second and fourth quadrant discharge shaping, so the overall power consumption of the equipment is large. This product can overcome these shortcomings.

technical characteristics

● Current, voltage and waveform data are directly obtained by high-voltage side sampling, and the data is true and accurate.

● Overvoltage protection: When the output exceeds the set pressure limit, the instrument will be shut down for protection, and the action time is less than 20 ms..

● Over-current protection: it is designed as dual protection of high and low voltage, and the high voltage side can be accurately turned off according to the set value;

● When the low-voltage side current exceeds the rated current, shutdown protection will be carried out, and the action time is less than 20 ms..

● The high-voltage output protection resistor is designed in the booster, and there is no need to connect another protection resistor.

● Due to the high and low voltage closed-loop negative feedback control circuit, the output has no volume increase effect.
