The device adopts power electronics technology, and the internal core part uses frequency conversion regulator. Digital control technology is used in parameter preset, protection setting, frequency selection and voltage regulation control. Built-in computer, 7 inch color LCD display, data storage can reach 256 groups.
Touch mode is adopted.
The test frequency of 50Hz, 100Hz, 150Hz and 200Hz can be preset (optional), and the voltage can be adjusted by touch mode (step size can be adjusted in real time, 1V, 2V, 5V, 10V) to realize the output of the multi-frequency test voltage of the device.
External LC filter circuit ensures that the waveform distortion rate is within the target range. External compensation inductance with tap is used to compensate the capacitive current of the tested equipment and improve the load capacity of the device.
Since the traditional three-phase five-column triple frequency generator is abandoned, the following advantages are brought about:
1. Small size, light weight, easy to carry, easy to high-power.
2. It not only generates triple frequency, but also generates 1, 2, 3 and 4 times frequency test voltage output.
3. The operation and wiring are simple, and the requirement of power supply capacity for field test is greatly reduced.
