3,Main functions of the system:
1) The variable frequency power supply adopts a linear power amplifier circuit, which has a perfect sine wave output and low waveform distortion
2) With automatic voltage stabilization adjustment function
3) Safe and reliable. A variety of protections are integrated in this device, including: discharge breakdown protection, over-voltage, over-current setting protection, output short-circuit protection, boot zero protection, bridge arm amplifier circuit protection, power curve protection, etc. When any kind of protection appears, the device immediately blocks the test voltage output and cuts off the main circuit power supply to ensure the safety of the test personnel, the tested product and the test system
4) The high-voltage measurement signal is transmitted by optical fiber to completely isolate the high-voltage and low-voltage circuits
5) Two control modes: automatic/manual
6) 320*240 dot liquid crystal display and multiple rotating mice provide a friendly man-machine interface, easy and quick operation and wiring, and truly "just look at it"
7) Synchronous voltage, current and frequency display
8) The output frequency is continuously adjustable within the range of 20-300Hz
9) The output voltage is continuously adjustable within the range of 0~350V
10) With resonance withstand voltage test function
11) With automatic resonant frequency search function, multiple automatic frequency sweeping frequency bands can be set


4,System display function:
1) With a large screen display, it can indicate: output voltage, output current, frequency, ambient temperature, outlet air temperature, variable frequency power supply output voltage waveform, date and time, countdown time, fault information, etc.;
2) It has the function of setting test parameters such as test voltage and time;


5,Other features of the product:
1) The oil-filled equipment in the device does not leak oil.
2) All metal shells in the device are rust-proof and anti-corrosion treatment, and the coating is uniform and beautiful. The main components have stainless steel nameplates and terminal signs.
3) The device can be stored, assembled and disassembled indoors and outdoors; the protection function is complete. The manufacturer guarantees that the control equipment, transformers, reactors, etc. of the device are at 1.1 times the rated voltage, and if the high-voltage side sample flashovers to the ground during the test, it will not cause personal injury and the test equipment will not cause harmful mechanical and thermal stress. Electrical performance is damaged or damaged.
4) Each part of the equipment has a nameplate that conforms to the national standard, the words and symbols are clear and durable, and the nameplate is clearly visible when the equipment is in normal operation.
