What kind of 主词六替换 will be higher(4)

power source is realized through the power transfer switch.
Modern UPS generally adopts pulse width modulation technology and modern power electronic devices such as power MOSFET, IGBT, etc., the noise of power supply can be reduced, and the efficiency and reliability can be improved. The introduction of microprocessor software and hardware technology can realize intelligent management of UPS, remote maintenance and remote diagnosis.
The maximum capacity of the online UPS can be made to 600kVA. The development of ultra-small UPS is also very rapid, and there are already 0.5kVA, lVA, 2kVA, 3kVA and other products of various specifications.

Electrolytic capacitors, aluminum electrolytic capacitors and monolithic gallbladders, which use sulfuric acid to make the insulating medium, large capacity can carry out smaller volumes for the above, and are marked with a + sign, some are marked with a mark, generally do low cross-linking and side-by-side Circuit filter with larger loss meson, integral aluminum electrolytic capacitor, due to the shortcomings of using special materials, the electrolytic performance is better than ordinary, the preferred frequency, but can not do too much capacity, it can be used to accurately circuits, such as oscillators, or timing circuits.

主词六替换Five: aging and batch test high temperature aging test

No matter how good the material and production technology process control of the product is, it is necessary to detect the aging of the equipment. Because the incoming inspection of electronic components and transformers is difficult to control, only by improving the aging and high-temperature sampling of the entire batch of power supplies can we detect whether the quality stability and material management of this batch of power supplies have potential safety risks.
