What is the difference between a UPS and a switching power supply?
The UPS is an uninterruptible power supply. It is an energy storage device that can be considered a battery;A switching power supply is a power supply that maintains a stable output voltage
UPS after power failure, still can maintain the equipment running for some time, often used in more important occasions, so that there is a period of time to buffer, good data storage. And there is a certain voltage regulator, and its input voltage although the regular is 220V or 110V (Taiwan, Europe and America), but sometimes it will be high and low, and after UPS, the output voltage to maintain a stable value.
Switching power supply is the 220V alternating current into direct current and required it can have multiple sets of DC output, internal main rectifier filter circuit, control circuit, because of its high efficiency and small volume, perfect protection, widely used in electronic equipment. Such as computers, televisions and so on.
Switching power supply a power failure is useless, and its connected devices immediately power off, there is the role of pressure change, the conventional 220V or 110V into 5V, 12V, 15V, etc...
The working voltage of household appliances in our country is AC 220V. What is the main difference between UPS and switching power supply?:UPS uninterruptible power supply, a battery and inverter circuit and control circuit, when the power supply is interrupted, the control circuit of UPS inverter circuit will detect and start work immediately, so that the output 220V alternating current, which is connected with the UPS electrical appliances continue to work for a period of time, so as to avoid the power interruption and losses.
