What is the difference between inverters and UPS?
Put it simply,An inverter is a current conversion device that converts a direct current into an alternating current or converts an alternating current into a direct current.UPS is an uninterruptible power supply device, its principle is battery + inverter, an inverter converts DC power, DC power to the battery, if the city electricity power, immediately into the battery through the inverter into alternating current, can be used directly for electrical appliances.The term "voltage regulator" is also mentioned here. The voltage regulator can maintain the unstable power supply at a fixed voltage by means of a voltage stabilizing device, which is very beneficial to the normal use of the electric appliance.
But because it is only one inverter current switching device, rarely used alone, the typical example is the vehicle power supply is an inverter, it takes 12 volt DC power from the car cigarette lighter, converted to 220 AC power for AC electrical appliances, such as notebook computer.
Some requirements are not too high, equipment will also use some back-up power supply system, such as emergency exit, the reaction is a bit slower, there is a standby engine more than 10 seconds power supply, but also the use of batteries. For example, the power plant itself power system, with millions of spare diesel units, all day long warm-up, once there is an accident power failure, guarantee ten or dozens of seconds to restore power supply.
UPS power is applied to the computer as such an unexpected power outage may cause loss of data such as electrical appliances, power is generally 1 seconds caused by the shutdown will start losing data, you can use UPS direct power supply protection, such as servers, Unicom mobile towers etc..
The term "voltage regulator" is also mentioned here. The voltage regulator can maintain the unstable power supply at a fixed voltage by means of a voltage stabilizing device, which is very beneficial to the normal use of the electric appliance.In civil use, voltage regulators are widely used, such as refrigerators and air conditioners, and many users install high-power regulators on the total incoming line, which makes all electrical appliances protected. We know that, especially after the power failure is resumed, the voltage will have an overload peak and the instantaneous voltage is too high. This is the reason why most of the electrical appliances are damaged.
