Product features
1. The series resonant device has protection functions such as overvoltage, overcurrent, zero position start, and system detuning (flashover). The overvoltage and overcurrent protection values can be set according to user needs. When the test sample flashes, the flashover protection action can be taken and the flashover voltage value can be recorded for experimental analysis.
2. The entire series resonant device is lightweight, not exceeding 40kg, making it easy to use on site.
3. The series resonant device has four working modes, which are convenient for users to flexibly choose according to the on-site situation and improve the test speed. The working modes are: fully automatic mode, manual mode, and automatic tuning manual boost mode.
4. It can store and print data in different locations, and the stored data numbers are numerical, making it convenient for users to identify and search.
5. The frequency starting point of the series resonant device during automatic frequency scanning can be set arbitrarily within the specified range, and the scanning direction can be selected upwards or downwards. At the same time, the LCD screen displays the scanning curve, making it convenient for users to intuitively understand whether the resonant point has been found.
6. Adopting DSP platform technology, it is convenient to add or remove functions and upgrade according to user needs, making the human-machine exchange interface more user-friendly.
