UPS and switching power supply what is the difference
Ups is an uninterruptible power supply, is a kind of energy storage device, can be seen as a battery;
The switching power supply is a power supply that maintains a stable output voltage
UPS is a power out, the computer can work for some time, the principle and the phone or laptop battery almost
UPS power can still maintain the equipment after a period of time, commonly used in more important occasions, so that there is a period of time to buffer, do a good job of data preservation. And there is a certain regulator, the input voltage although the conventional 220V or 110V (Taiwan, Europe and the United States), but sometimes will be high and low, then the UPS, the output voltage to maintain a stable value.
Switching power supply a power is useless, and its connected equipment immediately power, there is the role of pressure, the conventional 220V or 110V into 5v 12V 15V .... and so on.
China's household appliances operating voltage is AC 220V. UPS and switching power supply main difference is:
UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption.
Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.
