What is the difference between an inverter and a UPS power supply? An inverter is a current conversion device that can convert DC power into AC power, or convert AC power into DC power. UPS power supply is a system device that connects the battery to the host and converts DC power into commercial power through module circuits such as the host inverter. The following is a detailed introduction to the differences between inverters and UPS power supplies.
The difference between inverter and UPS power supply
Inverter power supply:
An inverter is a device that converts direct current (DC) into alternating current (AC). The power inverter (vehicle-mounted UPS power supply) is a convenient power converter that can convert DC12V direct current into AC220V alternating current, which is the same as the main power. It can be used by general electrical appliances.
UPS power supply:
UPS power supply is a constant voltage and constant frequency uninterruptible power supply containing an energy storage device and an inverter as the main component. UPS uninterruptible power supply connects the battery to the UPS host and converts direct current into alternating current through module circuits such as the UPS host inverter. It is mainly used to provide stable and uninterrupted power supply to computers and their network systems or other power electronic equipment.
What is the difference between inverter and UPS power supply?
1. The inverter power supply converts DC (direct current) to AC (alternating current), while the UPS power supply has three modes: bypass mode, mains mode, and battery mode.
2. Generally speaking, an inverter is just a converter and does not filter any electrical impurities. The device that converts DC power into AC power is called an inverter.
3. The bypass mode of the UPS power supply directly takes the main power without passing through the UPS power supply host. In the mains power mode, the mains power passes through the rectifier of the machine, filters the impurities of the mains power, and then passes through the inverter that comes with the host. The output supplies power to the device, while in battery mode, DC power (battery power) passes through the inverter and then is output to the device. This way the equipment is well protected.
4. UPS power supply is suitable for electrical appliances such as computers that may cause data loss due to unexpected power outages. Such electrical appliances will generally lose data if they are shut down due to a power outage of 1 second. UPS can be used for protection without indirect power supply, such as servers and China Mobile China Unicom. Signal transmission tower, etc. Because the inverter is just a current conversion device, it is rarely used alone. A typical example is a vehicle-mounted UPS power supply, which is an inverter. It takes 12V DC from the car cigarette lighter and converts it into 220AC. Used in AC appliances, such as laptops.
The similarities between inverter power supply and UPS power supply:
1. Provide a way to adjust voltage changes, eliminate various electrical interferences, and provide high-quality UPS power supply;
2. When the AC mains fail, the necessary backup power supply capability can be guaranteed. The biggest difference between the two is that UPS needs to be equipped with a battery pack and has a shorter backup time, while the inverter power supply does not need to be equipped with batteries and can directly use DC panels of various voltages in the communication room. Its capacity is large and can ensure network operation for a long time. Uninterrupted.
The above is all about the difference between inverter and UPS power supply. Inverter power supply and UPS power supply are two different things. They should be used according to different occasions. Choosing a suitable UPS will help to stabilize the power consumption of the equipment.
