Product Description
This device will be in resonant state by adjusting the inductance
value of the inductor or the working frequency of the whole system
or both methods. Adjust the frequency of the excitation transformer
to the required frequency, then adjust the inductance of the
inductor according the inductance value of the measured equipment,
make the system in resonant, and generate high voltage, if the
resonance point is deflected during the voltage boosting process,
can regulate the frequency to correctly find the resonance point to
ensure the high Q value, in order to farthest lessen the volume and
weight of the measured equipment and power capacity.
1. Device with over-voltage, over flow, zero start-up and loss of
harmonic flashover protection, overvoltage and current protection
value can according to user needs setting,flashover protection
action and can remember the flashover voltage value, for
experimental analysis.
2. The whole unit weight is very light, the maximum not more than
40kg, to facilitate the use of the scene.
3. The device has three modes of operation, which is convenient for
users to choose flexibly according to the field condition, and the
test speed is improved.
4. Working mode is: automatic mode, manual mode, automatic tuning
manual boost mode.
5. Can store and print data in different places, the data stored in
the number is digital, easy to help users to identify and find.
6. Device automatic sweep frequency starting point can be within
the scope of the provisions set arbitrarily, sweep direction can be
upward, downward selection, also the large screen liquid crystal
display scanning curve, convenient user intuitive understand
whether find resonance point.
