1.high performance, low loss, is a replacement for the 9 series.
2.the selection of high-quality silicon steel sheet, while significantly reducing the magnetic flux density, reducing the amount of magnetostriction of the silicon steel sheet during operation, effectively reducing noise.
3.Optimize the structure of the high-voltage coil, improve the distribution of voltage and capacitance between the layers, greatly improve the impact resistance of the product to withstand atmospheric over-voltage and operating over-voltage, and also improve the electric field distribution, so that the product volume is further reduced.
4.The temperature control system and air-cooling device can be configured to automatically start the fan cooling device when the load is too large, effectively improving the overload capacity of the equipment.
