Product Description

The third generation SVLF series Ultra-Low-Frequency High Voltage Generator

The third generation of advantages:

  • Waveform without distortion: Standard sine wave output.
  • Strong load capacity: load capacitance to meet the rated capacity(0.1Hz 1.1uF, 0.05Hz 2.2uF, 0.02Hz 5.5uF).
  • Little impact pulse current: Cyclo converter pulse current generated little impact on the grid.
  • Strong EMI immunity: During the test controller is stable and reliable.
  • Simple operation: Capacitive screen operation, simple and convenient.

Performance Characteristics:

  • Advanced inverter technology: Digital AC-AC inverter technology, advanced software closed-loop control, precise standard output without distortion sine wave, fully automated testing process.
  • Display: The 7 'capacitive touch screen, the screen displays real-time measurement data and the output waveform.
  • Comprehensive protection: high, low pressure side of the over-voltage and over-current protection, rapid response action (action time 10ms).
  • Simple operation: simple wiring, fool type operation.
  • Safe and reliable: the controller and the high voltage generator connected to the low pressure, photoelectric control, safety and reliability.
  • The high and low voltage closed-loop negative feedback control circuit, the output can not rise effect.
  • Test range: 0.1 Hz, 0.05Hz and 0.02Hz multi frequency selection, large measuring range.
  • Printer: print the test results.
  • Small size, light weight: very conducive to outdoor work.
  • Communication interface: USB2.0.
  • Software: Equipped with specialized SVLF ultra low frequency high-voltage generator software, can be tested by software, and the data query and print statements.

Power Supply

  • AC220V 10%, 50Hz 5%


  • If you use a portable generator power to require the generator output voltage and frequency stability (generally require power greater than 3kW, frequency 50Hz, voltage 220V 5%, and preferably with a 1kW load), or to use some auxiliary measures to stabilize the generator output .
  • Output voltage accuracy
