III. Device characteristics and working principle
The device adopts power electronics technology, and the internal core part uses a variable frequency regulator. Parameter presetting, protection settings, frequency selection, voltage regulation control, etc., all adopt digital control technology. Built in computer, 8-inch color LCD display, data storage can reach 3200 sets.
Adopting a touch based operation method and equipped with a thermal printer for Chinese character printing.
The device can preset test frequencies of 50Hz, 100Hz, 125Hz, 150Hz, and 200Hz (frequencies can also be set arbitrarily within the range of 45-200Hz), and adjust the voltage through touch (the step size can be adjusted in real time, selecting 1V, 2V, 5V, and 10V), which can achieve multi frequency test voltage output of this device.
External LC filtering circuit ensures that the waveform distortion rate is within the specified range. External compensation inductance with tap to compensate for the capacitance current of the tested equipment and improve the load capacity of the device.
Due to the abandonment of the traditional generation principle of three-phase five column triple frequency generators, the following advantages have been brought about:
1. Small size, light weight, easy to carry, and convenient for high-power conversion.
Not only can it generate three times the frequency, but it can also produce test voltage outputs of 1, 2, 3, and 4 times the frequency.
3. The operation and wiring are simple, which greatly reduces the requirement for on-site test power capacity.
