What does a 24V power supply look like?(5)

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.

Regardless of how much control the product material and production process are, aging needs to be checked. Because the incoming inspection of electronic components and transformers is difficult to control, the quality stability of this batch of power supplies and whether the materials are detected to have potential safety hazards can only be detected through aging and high-temperature sampling of the entire batch of power supplies.
