Product Description

Product Introduction

 This product combines modern digital frequency conversion technology and adopts microcomputer control, with automation for boosting, reducing voltage, measurement, and protection.
  Due to its digitization, it has a small size, light weight, large screen LCD display, clear and intuitive display, and can display output waveforms and print test reports. The design indicators comply with the power industry standard of "General Technical Conditions for Special Test Instruments for Power Equipment, Part 4: General Technical Conditions for Ultra Low Frequency and High Voltage Generators", which is very convenient to use.
  At present, both domestically and internationally, mechanical methods are used for modulation and demodulation to generate ultra-low frequency signals, resulting in non-standard sine wave waveforms, large measurement errors, spark discharge in the high-voltage part, bulky equipment, and high-power high-voltage resistors for discharge shaping in the second and fourth quadrants of the sine wave. Therefore, the overall power consumption of the equipment is relatively high. This product can overcome these shortcomings.

Functional features:

  Ultra low frequencies with a rated voltage less than or equal to 50kV adopt a single connected structure (one booster); Ultra low frequencies greater than 50kV adopt a series structure (two boosters are connected in series), greatly reducing the overall weight and enhancing the load capacity. Moreover, the two boosters can be used separately for low voltage level ultra-low frequencies.

 The current, voltage, and waveform data are all directly sampled from the high-voltage side, so the data is accurate.

 Equipped with overvoltage protection function, when the output exceeds the set voltage limit value, the instrument will shut down for protection, with an action time of less than 20ms. Equipped with overcurrent protection function: designed for dual protection of high and low voltage, with shutdown protection on the high voltage side according to the set value; When the current on the low-voltage side exceeds the rated current, shutdown protection will be implemented, and the action time will be less than 20ms.

  The high-voltage output protection resistor is designed within the boosting body, so there is no need to connect another protection resistor outside. Due to the use of a high and low voltage closed-loop negative feedback control circuit, the output has no capacitance rise effect.
